Preface The second edition of this PocketGuide to treatment procedures in speech-language pathology has been updated and expanded by more than 100 pages. Information on ethnocultural variables that affect treatment has been added under each disorder and the steps involved in administering certain treatment procedures are described in more detail in the second edition. Simultaneous revision of the companion volume, Hegde’s PocketGuide to Assessment in Speech-Language Pathology has also helped to streamline the information in the two books. This PocketGuide to treatment procedures in speech-language pathology has been designed for clinical practitioners and students in communicative disorders. The PocketGuide combines the most desirable features of a specialized dictionary of terms, clinical resource book, and textbooks and manuals on treatment. It is meant to be a quick reference book like a dictionary because the entries are alphabetized; but it offers more than a dictionary because it specifies treatment procedures in a ‘‘do this’’ format. The PocketGuide is like a resource book in that it avoids theoretical and conceptual aspects of procedures presented; but it offers more than a resource book by clearly specifying the steps involved in treating clients. The PocketGuide is like standard textbooks that describe treatment procedures; but it organizes the information in a manner conducive to more ready use. By avoiding theoretical background and controversies, the PocketGuide gives the essence of treatment in a stepby-step format that promotes easy understanding and ready reference just before beginning treatment. The PocketGuide does not suggest that theoretical and research issues are not important in treating clients; it just assumes that the user is familiar with them. How the PocketGuide is Organized Each main entry is printed in bold and burgundy color. Each cross-referenced entry is underlined in burgundy. Each main vii
Preface disorder of communication is entered in its alphabetical order. Subcategories or types of a given disorder are described under the main entry (e.g., Broca’s Aphasia under Aphasia). Specific techniques, most of them with general applicability across disorders (e.g., Modeling, Biofeedback, or Turn Taking) also are alphabetized. Such specific techniques generally are described at their main alphabetical entry (e.g., Modeling under M). When appropriate, the reader also is referred to the disorders for which the techniques are especially appropriate. For most disorders, a general and composite treatment procedure is described first. For example, there is a general treatment program described for Stuttering, Treatment or Language Disorders in Children. Following this description of a generic treatment procedure, specific techniques or treatment programs are described (e.g., treating auditory comprehension problems in aphasia, pragmatic problems in language disorders in children, or rate reduction in stuttering; and such treatment programs as Helm Elicited Program for Syntax Stimulation or the Monterey Fluency Program). Organization of entries varies somewhat for different disorders, but an example of a general organization used in the guide follows: Articulation and Phonological Disorders. (Definition) A General Articulation Treatment Procedure Treatment of Articulation and Phonological Disorders: Specific Techniques or Programs Behavioral Approaches Contrast Approach Cycles Approach Distinctive Feature Approach Multiple Phoneme Approach Paired Stimuli Approach Phonological Knowledge Approach Phonological Process Approach Sensory Motor Approach Traditional Approach

Preface Many treatment concepts and procedures are crossreferenced. All cross-referenced entries are underlined in burgundy. Therefore, the reader who comes across an underlined term can look up that term in a different place or context. How to Use This PocketGuide There are two methods for the clinician to use this guide. In the first method, the clinician looks up treatment procedures by disorders in their alphabetical order; an Abbreviated Contents: Entries by Disorders on page v will quickly refer the reader to specific communication disorders described in the guide. Treatment procedures of the following major disorders are described in their alphabetical order: Aphasia Apraxia of Speech Articulation and Phonological Disorders Cerebral Palsy Cleft Palate Cluttering Dementia Dysarthria Dysphagia Hearing Impairment Language Disorders in Children Laryngectomy Right Hemisphere Syndrome Stuttering Traumatic Brain Injury Voice Disorders Under each of the main entries for major disorders, the clinician may look up subentries or specific types of disorders. For example, under Dysarthria, the clinician will find the following alphabetized subentries and their treatment procedures:
ix
Preface Ataxic Dysarthria Flaccid Dysarthria Hyperkinetic Dysarthria Hypokinetic Dysarthria Mixed Dysarthria Spastic Dysarthria Unilateral Upper Motor Neuron Dysarthria In the second method, the clinician looks up treatment procedures by their name. For example, the clinician can look up such specific treatment techniques as the following in their alphabetic order: Activity-Based Language Intervention Airflow Management in Stuttering Augmentative Communication Behavioral Momentum Child-Centered Approaches to Language Intervention Collaborative Model Conversational Repair Delayed Auditory Feedback Differential Reinforcement of Alternative Behaviors (DRA) Environmental Language Intervention Strategy Event Structure Functional Equivalence Training Joint-Action Routines Incidental Teaching Method Isolated Therapy Model Mand-Model Melodic Intonation Therapy Narrative Skills Training Prolonged Speech x
Preface Rate Reduction in Treating Dysarthria Whole Language Approach and so forth. If appropriate, the reader who finds a specific treatment technique in the general alphabetized order is referred to the specific disorder for which the technique is relevant. A Caveat Serious attempts have been made to include most treatment techniques described in the literature. However, the author is aware that not all techniques have been included. Some have been excluded because of their transparent lack of logic, appropriateness, or even an expectation of desirable effects. A few are defined because they are popular or being advocated. However, they are not described fully because of the presence of strong negative evidence. Most important, in any task such as this that requires encyclopedic review of literature, omission of a procedure that deserves inclusion is an acknowledged and unintended limitation. The reader may be more often correct in assuming that a technique was omitted inadvertently than to assume that it was considered and rejected. The author did not set for himself the impossible goal of including all treatment techniques. The practical goal was shaped more by such descriptors or qualifiers of treatment techniques as the most, the major, the generally effective, the most widely practiced, and so forth. Such qualifiers necessarily involve judgment, with which clinicians will disagree. If some techniques included do not meet these qualifiers, that is fine; the author would rather err in that direction. Conversely, errors of omission are correctable through future revisions of this book. Therefore, the author is open to suggestions from clinicians and researchers. Although most treatment techniques in communicative disorder are in need of treatment effectiveness or efficacy data, those that are especially deficient are noted in their description xi
Preface or definition. Those treatment techniques that have especially strong supportive evidence also are noted. In most cases, unfortunately, information on effects and efficacy is unavailable or ambiguous. This guide is not a means of evaluating treatment techniques; such evaluation is solely the responsibility of the clinician who selects treatment techniques. To help the clinician make such evaluations, procedures and experimental designs that are used in treatment efficacy research are included in this guide. Also included are suggested Treatment Selection Criteria. Abbreviation Used Throughout the Book PGASLP: Hegde’s PocketGuide to Assessment in Speech-Language Pathology (2nd ed.) by M. N. Hegde (2001).

ABA Design A ABA Design. A single-subject research design used to evaluate treatment effects; a target behavior is first baserated (A), taught with the procedure to be evaluated (B), and then reduced (A) by withdrawing treatment to show that the teaching was effective. ● Baserate the target behavior to be taught ● Apply the new treatment to be evaluated ● When the target behavior increases, withdraw treatment ● Chart the results to show that the results for the baserate and withdrawal conditions were similar but those for the treatment condition were different.
ABAB Design. A single-subject research design used to evaluate treatment efficacy; a target behavior is first baserated (A), taught by applying the treatment program (B), reduced by withdrawing or reversing the treatment (A), and then taught again by reapplying the treatment (B) to show that the teaching was effective. The design has two versions: Reversal and Withdrawal. ● Baserate the behavior to be taught ● Apply the new treatment to be evaluated for the target behavior ● Briefly, apply treatment to another behavior or simply withdraw treatment ● Again treat the target behavior ● Chart the results to show that the two no treatment conditions were convincingly different from the two treatment conditions.
ABAB Reversal Design. A single-subject design for evaluating treatment effects; a desirable behavior is baserated (A), taught (B), reduced by teaching its counterpart (A), and then taught again (B) to show that the teaching was effective. ● Baserate the behavior to be taught ● Apply the new treatment to be evaluated for the target behavior 2
ABAB Withdrawal Design A ● Briefly, apply treatment to an incompatible behavior ● Again treat the target behavior ● Chart the results to show that the behavior varied accord-
ing to the treatment and reversal operations
ABAB Withdrawal Design. A single-subject research design for evaluating treatment effects; a desirable behavior is baserated (A), taught (B), reduced by withdrawing the treatment (A), and then taught again (B) to show that teaching was effective. ● Baserate the target behavior to be taught ● Apply the new treatment to be evaluated ● When the behavior increases, withdraw treatment ● Reapply treatment to the target behavior ● Chart the results to show that the behavior varied according to the treatment and withdrawal operations Hegde, M. N. (1994). Clinical research in communicative disorders: Principles and strategies (2nd ed.). Austin, TX: Pro-Ed.
Abduction. Separation of the vocal folds. Adduction. Approximation of the vocal folds. Agraphia. Loss or impairment of writing skills associated with cerebral pathology or injury; may be associated with reading problems (Alexia); not the same as writing problems found in children; often found in patients with aphasia; for treatment procedures, see Treatment of Aphasia: Writing Problems; see PGASLP for description of different types and assessment procedures.
Airflow Management. A stuttering treatment target; includes inhalation of air, slight exhalation before initiating phonation, and sustained air flow throughout an utterance; for procedures see Stuttering, Treatment; Treatment of Stuttering: Specific Techniques or Programs.
Alaryngeal Speech. Speech without a biological larynx; a mode of communication for persons whose larynges have 3
Alerting Stimuli A been surgically removed; may be electronically assisted, pneumatically assisted, or esophageal; for treatment procedures, see Laryngectomy.
Alerting Stimuli. Various means of drawing the client’s attention to the imminent treatment stimuli; include such statements as ‘‘Get ready! Here comes the picture!’’ or ‘‘Look at me, I am about to show you how,’’ or such nonverbal cues as touching the client’s hand just before presenting a stimulus.
Alexia. Reading problems in children and adults; in children, often due to inadequate instruction or learning disabilities; in adults, often due to neurological problems and is associated with aphasia, dementia, and related disorders; some use the term dyslexia synonymous with alexia; others apply the term dyslexia to reading problems in children whose instruction is adequate; may be associated with writing problems (Agraphia) in some, isolated in others; for treatment of alexia in patients with neurological communication disorders, see Treatment of Aphasia: Reading Problems; see PGASLP for description of different types of alexia and their assessment.
Alphabet Board. A communication board with the alphabet printed on it; may also contain a few words and sentences; the client simultaneously speaks and points to the first letter of each spoken word printed and displayed on the board; helps slow down the rate of speech in clients whose speech rate is excessive (e.g., clients with hypokinetic dysarthria).
Alphabet Board Supplementation.
A technique used in reducing the speech rate and thus improving intelligibility in clients with dysarthria; to reduce rate, the method requires clients to point to the first letter of each word on an alphabet board. ● Arrange an alphabet board with large capital letters ● Ask the client to point to the first letter of each word to be spoken on the board

Alternating Motion Rates (AMR) A Yorkston, K. M., Beukelman, D. R., Strand, E. A., & Bell, K. R. (1999). Management of motor speech disorders in children and adults. Austin, TX: Pro-Ed.
Alternating Motion Rates (AMR). A measure of the speed with which certain syllables (e.g., ‘‘puh, puh, puh’’) are repeated when asked to; the same as the diadochokinetic rate; used in the assessment of dysarthria or articulation disorders in children; see PGASLP for assessment procedures.
Alternative Communication.
Methods of nonoral, nonvocal communication that serve as alternatives to oral speech and language; only in a few extreme cases are the methods totally alternative; most nonoral, nonvocal means of communication augment oral and vocal communication; treatment techniques described under Augmentative Communication, a term some prefer.
Alzheimer’s Disease.
A degenerative neurological disorder caused by Neurofibrillary Tangles, Neuritic Plaques, Granulovacuolar Degeneration, and neurochemical changes; characterized by deterioration in behavior, cognition, memory, language, communication, and personality; most common of the irreversible dementias; consider the following suggestions and see Dementia for management details:
Management of Patients With Alzheimer’s Disease: General Guidelines ● A thorough assessment of not only the patient, but also
of the family resources and needs is necessary before rehabilitation can be started; see the cited sources and the PGASLP ● Management of symptoms and behaviors of the patient for as long as possible is a practical clinical goal of rehabilitation ● Counseling and supporting the family and teaching them the skills to cope with the disease are important elements of rehabilitation
5
Alzheimer’s Disease A ● Finding resources and services for disadvantaged fami-
lies and ethnoculturally diverse families is a part of rehabilitation ● Putting the family in touch with local support groups and national information centers on dementia and Alzheimer’s disease is useful to the families ● Some patients with Alzheimer’s disease may have a slow progression with several years of relatively stable behavior patterns; rehabilitation efforts with such patients and their families may be especially productive ● Family members and caregivers should not automatically assume that a patient with Alzheimer’s disease is incapable of making decisions in the early and middle stages of the disease Working With Caregivers and Family Members Ask caregivers and family members to: ● Use good lighting when communicating with the patient, especially if the patient has a visual-perceptual deficit ● Initiate interaction in a helpful manner • approach the patient within his or her visual field; do not surprise the patient • establish eye contact before speaking • always identify yourself before you start saying something; remind the patient about your earlier encounters, activities done together, and so forth • speak slowly to the patient ● Keep communication at a simple level but not overly simplified • keep your instructions simple and direct • use gestures, smile, and posture to enhance your verbal communication • ask the patient to do one thing at a time; avoid multiple and sequentially given commands • speak clearly

7
Alzheimer’s Disease A • keep only the shoes he or she uses • reduce desktop, coffee table, and countertop clutter ● Provide printed prompts for actions • print the patient’s daily schedule on a poster board • post it in more than one, conspicuous place • teach the patient to consult the schedule frequently (note that just posting notices may not do any good to the patient who may not consult them) • print only the essential information; keep displays simple ● Help support the patient’s continued orientation to time, place, persons, and events • help support the patient’s familiar activities, interests, and hobbies (let the patient watch his or her familiar TV shows, listen to music, engage in recreational activities) • make recent pictures of family members, family cars, home, and so forth and show them frequently to the patient to help keep orientation • frequently ask orientation questions (e.g., ‘‘Where are you?’’ ‘‘What day is it today?’’ ‘‘What time is it?’’); reinforce the patient’s correct answers; model and have the client imitate correct answers if the responses are incorrect • ask multiple choice questions about orientation (e.g., ‘‘Is this Friday or Saturday?’’ ‘‘Are you at home or in a hospital?’’) • post printed signs about the place, date, month, and year in clear view of the patient and in multiple settings; teach the patient to use them frequently • frequently remind the patient about the day, date, time, month, and so forth • post a larger calendar the patient can see often and mark the current day with a color border or some such device 8
Alzheimer’s Disease A • keep up the patient’s habit of looking at the clocks and reading the time; reinforce the client for correctly reading the time • keep a map of frequently visited places (e.g., homes of relatives and friends, shops, restaurants) • when prompting the patient to perform an action or attend an event, remind him or her of the day and time as well (e.g., ‘‘It’s 3 o’clock on Tuesday; time to watch the ------ show on TV.’’) • note that orientation problems are confounded with memory impairments; therefore, help sustain memory skills to the extent possible ● Minimize stimulation and reduce the frequency of events that disrupt the patient’s behaviors • reduce noise and loud music • have only a few people visit at any one time • reduce or eliminate loud and big parties • eliminate any chaotic situation • teach grandchildren to play more quietly around the patient ● Reduce or eliminate products and situations that pose danger to the patient • lower the thermostat on the hot water heater to reduce the danger of burning while taking a shower • keep all chemical cleaners, medications, manual and power tools (e.g., hammers, all kinds of saws, lawn mowers, grass edgers, sledgehammers and such other tools in the garage) out of the patient’s reach and preferably under lock and key • remove stove knobs or install special devices to turn them on • keep the family car keys in a secured place Direct Management of Communication and Memory Skills ● Teach superordinate category names (e.g., tools and furniture) instead of basic level names (e.g., socket 9

American Indian Hand Talk (AMER-IND). A system of nonverbal communication used by Native Americans to communicate with members of other tribes with different languages; a manual interlanguage; the signs represent ideas and many are pictographic; gestures may be produced in series to express more complex ideas, called agglutination; many signs are one-handed; used in teaching Augmentative Communication, Gestural (Unaided). American Sign Language (ASL or AMESLAN). A highly developed manual (gestural) language used mostly by deaf persons in the United States; a communication target for certain nonverbal or minimally verbal persons; each sign or gesture may represent a letter of the English alphabet, a word, or a phrase; signs provide phonemic, morphologic, 10
Amyotrophic Lateral Sclerosis (ALS) A and syntactic information; used in teaching Augmentative Communication, Gestural (Unaided).
Amyotrophic Lateral Sclerosis (ASL). A progressive neurological disease in which the upper and lower motor neurons degenerate; initial symptoms vary depending on the neurons involved, but in the final stages all levels of motor neurons are involved; symptoms of the final stage include severe impairment of movement; one of the several causes of dysarthria.
Analogies. Logical inferences that are based on the assumption that if two things are similar in certain aspects, then they must be alike in other aspects.
Anomia. Difficulty in naming people, places, or things; a major symptom of Aphasia.
Antecedents. Events that occur before responses; stimuli or events the clinician presents in treatment. Antecedents may be: ● Objects ● Pictures ● Re-created or enacted events ● Instructions, demonstrations, modeling, prompting, manual guidance, and other special stimuli
Aphasia. A language disorder caused by recent brain injury in which (a) all aspects of language comprehension and production are impaired to varying degrees (a nontypological definition); (b) one or more aspects of language comprehension and language production may be affected (a typological definition).
Treatment of Aphasia: General Guidelines
● Conduct a detailed assessment; see the cited sources and
PGASLP
● Reduce the effects of the residual deficits on the personal,
emotional, social, family, and occupational aspects of the client’s life 11
Aphasia: General Guidelines A ● Teach compensatory strategies (e.g., signing, gestures) ● Counsel family members to help them cope with the re-
sidual deficits
● Give a realistic prognosis that modifies the clients’ and the
family members’ expectations
● Structure the treatment and let the client repeatedly prac-
tice the target behaviors
● Develop a variety of client-specific treatment procedures ● Exploit the client’s strengths (e.g., use the stronger visual
mode to supplement the weaker auditory mode)
● Judge when it is not useful or ethical to continue the
treatment
● Observe the client carefully ● Choose client-specific target behaviors that enhance func-
tional communication rather than grammatical correctness
● Sequence target behaviors in treatment ● Move from simple to complex tasks ● Use such extra stimuli as instructions, prompts, modeling,
pictures, and objects in initial stages of treatment
● Fade extra stimuli used in treatment ● Use only natural stimuli (e.g., only a question, not a
prompt) to evoke speech in later stages of treatment
● Program natural consequences for functional communica-
tion targets (e.g., smile and approval to reinforce verbal expressions; real objects to reinforce requests for objects) ● Provide immediate, response-contingent feedback ● Encourage the client to self-monitor ● Train family members to evoke, prompt, reinforce, and maintain communicative behaviors
Treatment of Aphasia: Ethnocultural Guidelines Consider the ethnocultural, linguistic, and economic background of the client in planning treatment. There is little or no controlled experimental research on the effectiveness of different treatment approaches when applied to different ethnocultural clients with aphasia. However, the clinician should: 12
Aphasia: Ethnocultural Guidelines A ● Gain an understanding of the client’s family and its eco-
● ●
●
●
● ●
● ●
nomic resources to pay for extended treatment, afford regular transportation, ability and willingness to keep regular appointments Help find public and private resources that support a client’s continued treatment and rehabilitation Assess the family members’ educational level, emphasis on communication skills, and their willingness and time available for helping the client Understand the client’s family constellation and communication patterns (e.g., living in an extended family; the client’s role in educating and raising grandchildren) Evaluate client’s linguistic background and especially if the client speaks a different dialect or form of standard English (e.g., African American English or Spanish-influenced English); premorbid literacy level and the current need for literacy skills (e.g., Does the client need treatment for reading and writing or will functional communication suffice?) Assess communication needs of a bilingual client in both languages or, at the least, in the dominant language Select treatment targets that are functional and effective in the client’s natural environment and are appropriate for the communicative needs of the client and the family Select treatment stimuli that are available in the client’s home, and, if appropriate, work environment Carefully describe the treatment procedures and note the effects they produce or fail to produce; modify the treatment procedure in light of the client’s performance and ethnocultural background

Treatment of Aphasia: Auditory Comprehension In planning auditory comprehension treatment, consider the following factors that promote better comprehension in an aphasic patient: 13
Aphasia: Auditory Comprehension A ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ●
● ● ●
More frequently used words Nouns rather than verbs, adjectives, and adverbs Picturable verbs and other words Unambiguous pictures Shorter sentences Syntactically simpler sentences Active sentences Personally relevant information Slower speech with frequent pauses Slower rate with additional stress on key terms Speech in quieter environment Redundant messages Repeated verbal messages Connected speech rather than isolated words or sentences Limited response choices Accompanied auditory stimuli with appropriate visual stimuli Visibility of the speaker’s face Alerting Stimuli presented before the evoking stimulus is presented (e.g., ‘‘Look at my face.’’ ‘‘Here comes the picture.’’). In treating auditory comprehension, avoid the following that are known to be detrimental to improved auditory comprehension: Louder speech, which is generally ineffective Telephone presentations, which may have a negative effect in some clients Audio- or videotaped presentations, which are ineffective
Sequence of Auditory Comprehension Treatment Comprehension of Single Words Ask the client to point to: ● Body parts ● Objects ● Pictures of objects ● Clothing items ● Food items ● Actions in pictures 14
Aphasia: Auditory Comprehension A Comprehension of Spoken Sentences Accept an appropriate verbal or nonverbal (gestural) response that suggests comprehension. Treat comprehension of: ● Simpler sentences before more complex sentences ● More redundant sentences before less redundant sentences ● Sentences with familiar information before those with unfamiliar information Comprehension of Spoken Questions Ask questions of the following kind and accept a correct verbal or nonverbal response of any length or complexity: ● Concrete yes/no questions (‘‘Are you sitting in the wheelchair?’’) ● Abstract yes/no questions (‘‘Is a plant bigger than a tree?’’) ● Simpler open-ended questions (‘‘What pet do you have?’’) ● More complex open-ended questions (‘‘How many states are in the United States?’’) Comprehension of Spoken Directions ● Start with pointing to, and manipulation of, objects: • point to single objects (nouns) or actions in pictures (single verbs) • point to objects in sequence (‘‘Point to the pen and then the paper.’’) • manipulate stimuli in sequence (‘‘Point to the pen and then lift up the paper.’’) • manipulate objects according to directions (‘‘Put the ball in the box.’’) ● Use Manual Guidance if the client cannot point to the pictures (e.g., take the client’s hand and make it touch the requested objects) Comprehension of Discourse Target such skills as: 15
Aphasia: Verbal Expression A ● Understanding narratives (e.g., tell or read a short
story aloud and ask questions to test comprehension of details and the main story idea) ● Understanding questions in a conversational format (asking questions about personal interests and hobbies while engaging the client in conversational speech)
Treatment of Aphasia: Verbal Expression Treatment of Naming: Designing Problem-Specific Strategies Design treatment to suit the kind of anomia present: ● Word production anomia: Anomia due mainly to motor problems; often does not need direct treatment; provide such simple cues as the first sound of target words. ● Word selection anomia: Clients can describe, gesture, write, and draw to suggest a word they cannot say or can correctly recognize the name when given; cueing, including gestures, descriptions, and drawing is not very effective. ● Semantic anomia: Patients do not recognize the words they cannot produce; train word recognition. ● Limited anomia: Disconnection anomias; such category-specific problems as difficulty naming animals or vegetables; pair unimpaired skills with impaired naming. ● Delayed response: Presumably due to the slow activation of the naming process; shape progressively faster reaction time. ● Self-corrected errors: Prompting might be effective; reinforce self-correction. ● Perseveration: Persisting errors; reduce their frequency. ● Unrelated words: Irrelevant responses; reduce their frequency. Paraphasias: Unintended word or sound substitutions; reduce their frequency by increasing the production of target words. 16
Aphasia: Naming A Treatment of Naming: General Considerations Use stimuli or strategies that facilitate correct naming: ● High frequency words ● Names of manipulable objects ● Names of objects rather than pictures ● Realistic drawings rather than line or abstract drawings ● Phonemic cues ● Client-regulation of stimulus presentation ● Extra time to respond ● Longer (30 seconds or more) stimulus exposure time ● Simultaneous visual and auditory stimulus presentation Treatment of Naming: Targets and Techniques Confrontation Naming: Treatment Procedure. Confrontation naming is naming an object when asked ‘‘What is this?’’ ● Start with more familiar objects and move on to less familiar objects ● Place a picture or an objects in front of the client ● Ask ‘‘What is this?’’ ● Prompt the correct response ● Reinforce the correct response Naming in General: Treatment Procedure ● Use cueing hierarchies (Response evoking stimuli arranged in hierarchies) ● Find a stimulus (cue) that evokes the response ● Use a stronger cue only when weaker cues do not evoke the response ● Start with a few cues and add more only when necessary ● Use different types of cues ● Fade the cue so that natural stimuli come to evoke the response Types of Cues Modeling ● Ask a question (‘‘What is this?’’) 17
Aphasia: Naming A ● Immediately model the response (‘‘Say, a
book.’’)
● Let the client imitate ● Reinforce the client for correct imitation
Sentence completion tasks as cues: Give parts of sentences as cues. .’’ Clinician (CN): ‘‘You write with a Client (CT): ‘‘Pen.’’ CN: ‘‘ You write with a ball-point
.’’
CT: ‘‘Pen.’’ Initial sound of words as cues: Give initial sounds as cues. CN: ‘‘You write with a (pause); the word starts with a p .’’ CT: ‘‘Pen.’’ Syllables as cues: Give syllables of words as cues when the sound cue is not effective. CN: ‘‘This is a spoo
.’’
CT: ‘‘Spoon.’’ Silent phonetic gestures as cues: Give articulatory postures without vocalizations as cues. CN: ‘‘This is a for p).
.’’ (silent articulatory posture
CT: ‘‘Pen.’’ Functional descriptions as cues: Give a description of the use of an object as its cues. CN: ‘‘This is a round object that you roll or kick. What do you call it?’’ CT: ‘‘Ball.’’ Description and demonstration of an action as cues: Request the target name, describe its use, and demonstrate an action as cues. 18
Aphasia: Naming A CN: ‘‘What is this? You use this to write’’ (demonstrate writing). CT: ‘‘Pen.’’ Client description as cues: Ask a client to first say what an object is used for and then name it. CN: ‘‘Tell me what you use this for and then tell me its name.’’ CT: ‘‘I use it to write. It is a pen.’’ Patient’s demonstration of functions as cues: Ask the client to first demonstrate the function of an object and then name it. CN: ‘‘Show me how you use this and then tell me the name.’’ CT: Demonstrates the action of drinking and then says ‘‘cup.’’ Objects or pictures with their printed names as cues: Present an object or a picture with its printed name and ask the client to name it. CN: Presents a book (or a picture of a book), the printed word book, and then asks the client, ‘‘What is this?’’ CT: ‘‘Book.’’ Patient’s oral spelling as cues: Ask the client to spell a word orally and then say the word (name). Patient’s spelling and writing as cues: Ask the client to spell a word, write it, and then say it. An associated sound as a cue: Present a sound associated with an object and then ask the client to name it. An associated smell as a cue: Present an object and let the client smell the fragrance typically 19
Aphasia: Naming A associated with it and then ask the client to name it. A synonym as a cue: Say ‘‘dwelling’’ to evoke the word ‘‘house’’ from the patient. An antonym as a cue: Say ‘‘woman’’ to evoke the word ‘‘man.’’ A typically associated word as a cue. Say, ‘‘plate’’ to evoke the word ‘‘cup.’’ A superordinate as a cue: Say ‘‘It is something you eat’’ to evoke ‘‘cake.’’ A rhyming word as a cue: Say ‘‘It rhymes with hog’’ to evoke ‘‘dog.’’ Deblocking: Direct and Indirect. Treating naming or word-finding problems in clients with aphasia by presenting a variety of stimuli to which the person can respond and then presenting the target stimulus for the client to respond to. Direct deblocking: Present several unrelated words along with the target word (e.g., say several words along with ‘‘cup’’; then ask the client to name the picture of a cup) Indirect deblocking: Present a word typically associated with a target word and then ask the client to produce it; do not present the target word (e.g., say ‘‘woman’’ to evoke the word ‘‘wife’’). Fade the special cues: Gradually reduce the amount and extent of cues and ask typical questions to evoke naming; reinstate previously successful cues when necessary; again, try to fade them out. Teach self-cueing: Teach the client to first produce an antonym, a synonym, or an associated word that may lead to the target word; teach the client to first spell the word, de20
Aphasia: Expansion Expressions A scribe the use, demonstrate the use that may lead to the target word; teach the client to self-generate effective cues in natural settings.
Treatment of Aphasia: Expansion of Verbal Expressions. Expand words into phrases, phrases into sentences, and sentences into narratives and conversational speech. For expansion, select verbal expressions that are: ● Most useful to the client and his or her caregivers ● Most effective in expressing personal experiences, basic needs, emotions, and thoughts ● Most meaningful in social contexts to sustain conversation Teach Verbal Expressions ● While asking the client to describe scenes in a picture, model simple sentences for the client to imitate ● Fade the model and ask a question to evoke the sentence the client imitated ● Ask questions about the client’s daily activities ● Ask the client to describe actions in a picture ● Supply functional words and ask the client to make sentences with those words ● Tell a story and ask the client to retell it ● Tell a story and ask questions about the details ● Show sequenced pictures and ask the client to construct a story ● Give such cues as ‘‘say more’’’ or ‘‘elaborate on that’’ to have the client expand limited expressions ● Ask the client to describe such familiar tasks as making an omelet, planting flowers, or changing flat tires ● Engage the client in more naturalistic conversation ● Have family members engage the client in conversation in and out of the treatment setting ● Reinforce the client for correct or functionally appropriate productions 21
Aphasia: Functional Communication A ● Give corrective feedback (‘‘That is not correct’’; ‘‘That
was a wrong word’’; or ‘‘How about this
?’’)
● Repeat successful trials several times to strengthen the
responses
Treatment of Aphasia: Functional Communication and Maintenance Functional communication skills are those that are useful in social situations; final targets of aphasia treatment; in addition to the following generic treatment procedure, consider using one of several special programs described later in this section under Treatment of Aphasia: Specific Techniques or Programs; integrate compatible procedures. ● Target communication as opposed to linguistic accuracy ● Select words, phrases, and sentences that are most useful: • for the client and his or her caregivers • in expressing the client’s personal experiences, bodily needs, emotions, and thoughts • in simple, everyday social situations and conversational contexts ● Design client-specific treatment programs in which you shape progressively longer utterances ● Start with what the client can say, perhaps a few words or even syllables ● Add other syllables to create words, or words to create phrases ● Add additional words to create sentences ● Evoke a variety of sentence structures • noun and verb combinations • active declarative sentences • requests, commands, demands • wh-questions • structures with adjectives • structures with comparatives • yes/no questions
22
Aphasia: Functional Communication A ● ● ● ●

• structures with prepositions, pronouns, present progressives, and so forth Use special stimuli that are necessary (pictures, modeling, prompting, and so forth) Fade the special stimuli out, and fade in the naturalistic stimuli Reinforce the client productions Move to conversational speech • engage the client in meaningful, functional conversation • ask the client to describe personal experiences, hobbies, professional experiences, family-related events, favorite foods, entertainment, books read, vacations taken, and so forth • narrate a story and ask the client to retell it • role play Turn Taking • reinforce the client for staying on a topic; extend the duration of Topic Maintenance Implement a maintenance program • train the client to generate his or her own cues for better speech ➞ teach the client to self-monitor ➞ implement treatment in naturalistic settings ➞ use natural response consequences • conduct group sessions in which the clients learn to monitor and reinforce each other’s verbal or nonverbal expressions • train health care professionals to support and socially reinforce the communicative behaviors • train family members to ➞ evoke and reinforce speech ➞ reduce demands when it is appropriate ➞ pay attention to the client’s strengths ➞ express emotional support for the client ➞ include the client in communicative and other social activities
23
Aphasia: Reading/Writing Problems A Treatment of Aphasia: Reading Problems Treatment of reading problems may or may not be a major part of aphasia rehabilitation. When it is, use the following guidelines: ● Assess whether reading skills are important for the client ● Consider the level of premorbid reading skills and the current need to read ● Depending on the need, teach functional reading skills to persons who have mild or moderate aphasia ● Target comprehension of silently read material rather than oral reading ● Select client-specific, basic, and functional (survival) reading skills for treatment ● Target newspaper- and book-reading skills only when functional and basic reading skills are intact ● Teach comprehension of printed words in the beginning • Have the client read aloud selected printed words • Model and prompt the responses • Repeat successful trials for each word • Have the client read the words silently and state their meaning • Provide positive reinforcement and corrective feedback ● Construct phrases and sentences with words already comprehended ● Have the client read those phrases and sentences aloud with the help of modeling and prompting ● Have the client read them silently and state their meanings ● Present progressively complex reading material and assess comprehension at each level of complexity
Treatment of Aphasia: Writing Problems Treatment of writing problems may or may not be a major part of aphasia rehabilitation. When it is, use the following guidelines:
24
Aphasia: Apraxic Speech A ● Assess whether writing skills are important for the
client
● Consider the level of premorbid writing skills and the
current need to write
● Depending on the need, teach functional writing skills
to persons who have mild or moderate aphasia
● Consider the preferred hand and whether it is free from
neuromuscular disorders
● Consult with the client, family members, and other care-
● ● ● ● ● ● ● ● ● ● ●
givers to select words, phrases, and sentences that are important to the client and are useful in his or her daily living (e.g., names of family members, address and phone numbers, grocery lists, short letters, filling-out forms, writing down appointments) Target correct spelling of words and grammatical accuracy of sentences Name a target alphabet and have the client point to its printed form Name a target word and have the client point to its printed form Have the client trace printed letters and words Have the client copy letters and words Have the client write letters and words to dictation Have the client copy sentences Have the client spontaneously write sentences Have the client write paragraphs, short letters, lists, and so forth Give writing homework the client completes Train family members to help sustain the writing skills at home
Treatment of Aphasia: Apraxic Speech in Persons With Aphasia Persons with aphasia are likely to exhibit verbal apraxia or Apraxia of Speech, especially those who have Broca’s aphasia. Prognosis for severe apraxia beyond 4 weeks
25
Aphasia: Specific Types A postonset is thought to be poor. In treating apraxic speech in patients with aphasia, use the following guidelines: ● Make a thorough assessment of apraxia and its severity as treatment procedures vary somewhat, depending on the severity ● Note that clients with aphasia and apraxia do not necessarily have sound discrimination problems ● Auditory discrimination training to improve apraxic symptoms are unnecessary and unproductive ● An early suggestion that persons with aphasia and apraxia are deficient in oral sensation and oral form recognition has not been sustained ● Treatment procedures described under Apraxia of Speech are appropriate for patients who have both aphasia and apraxia of speech Brookshire, R.

Treatment of Aphasia: Specific Types of Aphasia Treatment suggestions offered for specific types of aphasia are based on the symptom complex and expert opinion. Substantive, experimentally validated treatment procedures that are specific to certain types of aphasia are limited. Treatment techniques with experimentally documented effects for such types as transcortical sensory aphasia and conduction aphasia are lacking. Clinicians 26
Aphasia: Broca’s A generally design behavioral procedures to teach and strengthen skills that are impaired and are judged appropriate for remediation in a given client. Broca’s Aphasia. A type of aphasia characterized by nonfluent, effortful speech with missing grammatical elements; marked difficulty in naming; slow rate of speech and limited word output; limited syntax; better auditory comprehension; may have associated dysarthria and apraxia of speech; usually associated with lesions in the third frontal convolution of the left or dominant hemisphere. ● Use procedures described under Aphasia; Treatment of Aphasia: Verbal Expression; specifically: • Increase length of utterances in gradual steps • Increase complexity of responses in gradual steps • Decrease grammatical errors • Treat naming difficulties • Decrease stereotypic utterances by giving corrective feedback • Use modeling • Model progressively longer utterances and ask the client to imitate • Teach nouns and verbs on successive trials • Provide immediate, positive feedback • Ask questions to evoke responses • Encourage pointing, gestures, drawing, writing, and reading to improve verbal expression • Teach a sign language system (e.g., AMER-IND) if necessary ● In addition, consider the following: • Combine gestures with verbal expressions as this combination is known to facilitate naming and other verbal expressions • Teach self-cueing strategies • Find out the compensatory strategies a client uses (e.g., singing, gesturing, or writing key words to 27
Aphasia: Global A effectively communicate) and incorporate them into training; reinforce their use in and out of the clinic • Reinforce even telegraphic productions and then model more complete productions using the client’s telegraphic productions • Reinforce the client’s imitation of more complete productions • Select one of the special programs described under Aphasia; Treatment of Aphasia: Special Programs (e.g., A Program of Changing Criteria, the Helm Elicited Language Program for Syntax Stimulation, or Promoting Aphasics’ Communicative Effectiveness or Response Elaboration Training) Global Aphasia. A type of aphasia characterized by severe deficits in comprehension and production of language; all sensory modalities may be affected; caused by widespread damage to language areas of the brain. ● Note that traditional aphasia therapy for some very severely globally aphasic patients may not be effective or appropriate; in such cases, train the health care staff and family members to: • be alert to the patient’s communicative efforts of any kind including eye contact, head nodding, facial expressions, postures, simple gestures, and so forth • not to expect linguistic accuracy and expansions • eliminate distractions while talking to the client • face the client while talking to him or her • draw the client’s attention before each attempt at communication • speak slowly • pause at syntactic junctures and between stimulus presentations • use appropriate stress and intonation • use short, simple sentences; simplify all messages • pause between sentences 28
Aphasia: Global A • • • •
use nonverbal cues to improve communication allow extra time for the client to respond be unhurried verbally state the guessed response from the client so he or she can confirm it • let the client know if there is difficulty in understanding him or her (e.g., ‘‘I am sorry, I do not understand.’’) To implement a more formal treatment program: ● Establish realistic goals for the client ● Use procedures to improve auditory comprehension of simple commands and requests ● Select basic, simple, functional words and phrases for initial treatment ● Teach yes/no responses to basic questions ● Teach a few unequivocal gestures to express basic needs ● Teach simple line drawing to express basic needs ● Select words and phrases that express basic needs ● Accept any mode of response: verbal, gestural, or signed ● Provide both auditory and visual stimulation; combine verbal responses with gestures ● Provide multiple stimuli (modeling, pictures, written stimuli, objects, gestures) ● Begin treatment with modeling and require immediate imitation ● Ask for delayed imitation later; give the client time to respond ● Fade modeling and other additional stimuli ● Shape the response to achieve more complex forms if found appropriate ● Provide manual guidance in shaping gestures, nodding the head, and pointing to objects ● Give prompt, natural, and social reinforcement ● Teach responses to simple questions 29
Aphasia: Transcortical Motor A ● Teach simple requests ● Teach simple descriptions ● Move to basic conversational skills training if judged
appropriate
● Improve writing skills if found necessary and ap-
propriate
● Teach an organized gestural system and consider
techniques described under Augmentative Communication (including AMER-IND, Communication Boards, and Blissymbolics). ● Consider one of the special programs (Aphasia; Treatment of Aphasia: Special Programs, including Visual Action Therapy and Gestural Reorganization) ● Counsel the family about the effects of stroke, the communication problems and prospects of treatment, home strategies to enhance communication, and so forth Collins, M. (1991). Diagnosis and treatment of global aphasia. San Diego: Singular Publishing Group.
Transcortical Motor Aphasia. A type of nonfluent aphasia characterized by agrammatic, paraphasic, and telegraphic speech; distinguishing feature is intact repetition; lesion is typically outside Broca’s area, found often in the deep portions of the left frontal lobe or below or above Broca’s area. Use imitation and naming to improve speaking ● Select pictures as stimuli • ask the client to say or write nouns and verbs that the pictures suggest • if the client fails, point out dominant aspects of the stimulus or prompt nouns and verbs • obtain from the client or supply three or more words for each picture ● Ask the client to form sentences with one of the words produced or supplied
30
Aphasia: Wernicke’s A ● Ask the client to expand the sentence with other
words
● Reinforce all attempts in the right direction
Use relatively intact reading skills to prime or promote speaking ● Begin treatment sessions with client reading general printed materials aloud to deblock speaking ● Begin controlled conversational treatment after an extended period of reading ● Relate conversation to the reading if necessary, or unrelated if possible ● Have the client read selected utterances (prepared for the client) and then say them if general reading does not deblock speaking ● Have the client read more complex materials and answer questions about them ● Model if necessary ● Use story books with pictures, ask the client to first read the story, and then describe the pictures in the same book Rosenbek, J. C., LaPointe, L. L., & Wertz, R. T. (1989). Aphasia: A clinical approach. Austin, TX: Pro-Ed.
Wernicke’s Aphasia. A type of fluent aphasia characterized by good or even excessive fluency of speech, rapid rate, normal articulation and prosody, good grammatical structures, paraphasia, neologism, jargon, and generally meaningless speech; poor auditory comprehension is a major distinguishing feature; the lesion is in Wernicke’s area. ● Reduce the impulsive and incessant talking: • structure the treatment sessions and reduce distracting stimuli • ask the client to listen • use gestures and manual guidance to stop the client from talking (touch your lips with your index

Treatment of Aphasia: Specific Techniques or Programs Gestural Reorganization. A method of teaching verbal expression by first pairing them with gestures and then fading the gestures; described by J. Rosenbek, L. LaPointe, and R. Wertz. ● Select phrases or sentences for training ● Select gestures that mean the same as those target expressions • use gestures from American Indian Hand Talk (AMER-IND) or other systems • invent gestures that are appropriate for the expressions • explain the gestures and the treatment approach to the client 32
Aphasia: Specific Programs A ● Teach the gestures to the client
• ask the client to match your gesture • ask the client to match pictures of gestures • teach functional and spontaneous use of gestures ● Combine the learned gestures with speaking (verbal expression) • model the gesture and the verbal expression • model only one of them • use Manual Guidance if necessary (manually help form the gesture) • have the client practice the two separately, only if necessary; combine them ● Fade the gestures and continue to evoke and reinforce the verbal expressions Rosenbek, J. C., LaPointe, L. L., & Wertz, R. T. (1989). Aphasia: A clinical approach. Austin, TX: Pro-Ed.
Helm Elicited Program for Syntax Stimulation. An aphasia treatment program designed to increase the production of syntactically correct utterances in agrammatic clients with moderate to well-preserved auditory comprehension and some speech production; developed by N. Helm-Estabrooks; uses pictures and a story completion method to evoke the following 11 sentence types at two levels (Level A and Level B): 1. Imperative Intransitive (‘‘Lie down.’’) 2. Imperative Transitive (‘‘Wash the dishes.’’) 3. Wh-interrogative (‘‘What are you doing?’’) 4. Declarative Transitive (‘‘She cleans teeth.’’) 5. Declarative Intransitive (‘‘She skates.’’) 6. Comparative (‘‘They’re funnier.’’) 7. Passive (‘‘The suitcases were lost.’’) 8. Yes/No Questions (‘‘Did you buy the paper?’’) 9. Direct and Indirect Object (‘‘They give Pat a cake.’’) 10. Embedded Sentences (‘‘She wanted him to be healthy.’’) 11. Future (‘‘He will hike.’’) 33
Aphasia: Specific Programs A Background and Preparation ● Obtain the entire treatment program or prepare your own questions, stories, and pictures ● Baserate the responses Level A ● Select sentence type 1. ● Read a story containing a target sentence; ask the client to produce the target sentence: Clinician (CN): ‘‘My friend feels dizzy, so I tell him, ‘lie down.’ What do I tell him?’’ Client (CT): ‘‘Lie down.’’ ● Upon reaching a 90% accuracy criterion, move to
Level B. Level B ● Read a short story again, but without the target sentence; ask the client to produce the target sentence: CN: ‘‘My friend feels dizzy, so I tell him what?’’ CT: ‘‘Lie down.’’ ● Upon reaching 90% accuracy criterion for sentence type 1 at Level B, select sentence type 2 for training; use the same procedure as for sentence type 1. ● Complete training on all 11 sentence types Helm-Estabrooks, N. (1981). Helm elicited program for syntax stimulation. Austin, TX: Pro-Ed. Helm-Estabrooks, N., & Albert, M. L. (1991). Manual of aphasia therapy. Austin, TX: Pro-Ed.
Melodic Intonation Therapy (MIT). An aphasia treatment program for clients with severe nonfluent aphasia with good auditory comprehension; developed by M. Albert, R. Sparks, and N. Helm; uses musical intonation, continuous voicing, and rhythmic tapping to teach verbal expression; hierarchically structured; contraindicated for clients with Wernicke’s, transcortical motor or sensory, and global aphasia; has three levels.
34
Aphasia: Specific Programs A General Procedures ● Select high probability words, phrases, and sentences ● Use pictures or environmental cues for each target utterance ● Intone each word, phrase, or sentence slowly and with constant voicing ● Maintain pitch and stress variations of normal speech ● Tap the client’s left hand once for each intoned syllable ● Signal with your left hand when to listen and when to intone ● Generally, move to the earlier step when the client fails at a step Level I ● Humming: Show a picture, hum the target item, and tap; no response required ● Unison singing: Intone in unison with the client and tap ● Unison with fading: Intone, tap, and fade halfway through the phrase ● Immediate repetition: Ask the client to listen to you as you intone the phrase and tap; let the client imitate ● Response to a probe question: Following a correct imitation, intone a probe question (e.g., ‘‘What did you say?’’) Level II ● Introduction of item: Intone the phrase twice and tap; no response required ● Unison with fading: Intone, tap, and fade halfway through the phrase ● Delayed repetition: Intone and tap, and after 6 seconds of delay, let the client tap with assistance; ask the client to intone without help
35
Aphasia: Specific Programs A ● Response to a probe question: Six seconds following
the client’s response, intone the probe question; do not hand tap; let the client intone the phrase Level III ● Delayed repetition: Tap and intone and let the client intone the phrase after 6 seconds and give tapping assistance ● Introducing sprechgesang (speech song): Present the target phrase twice slowly, without singing, but with exaggerated rhythm and stress; no tapping and no response required ● Delayed spoken repetition: Present the phrase in normal prosody, without hand tapping and let the client imitate after 6 seconds in normal prosody ● Response to a probe question: Ask a probe question with normal prosody after a 6-second delay; let the client respond with normal prosody Albert, M., Sparks, R., & Helm, N. (1973). Melodic intonation therapy for aphasia. Archives of Neurology, 29, 130–131. Helm-Estabrooks, N., Nicholas, M., & Morgan, A. (1989). Melodic intonation therapy program. San Antonio, TX: Special Press. See this source for a complete description of steps, scoring procedure, and stimulus materials.
Program of Changing Criteria. An aphasia treatment program described by J. Rosenbek, L. LaPointe, and R. Wertz to increase the length and quality of language; uses systematic shaping and progressively higher response criteria requiring longer utterances; uses differential reinforcement and extensive practice. ● Select realistic human action pictures to evoke responses ● Write about 10 questions, some of which you will use with each picture (e.g., ‘‘How many people do you see?’’ ‘‘What are they doing?’’ ‘‘What is the person wearing?’’) 36
Aphasia: Specific Programs A ● Begin at Criterion I. Require a one- or two-word
response • give directions, present a picture, and ask a question • if no or incorrect response, use the Cloze Procedure • if the client fails, model the response • if the client fails, use any other procedure to evoke the response • if the client fails, use another program • reinforce and give repeated practice on correct responses ● Move to Criterion II. Require a three- to five-word response • give cloze-like cues when the response is incorrect • if the client fails, model the correct response • if no imitation, use any other method to evoke the response • if still no success, return to Criterion I or shift to another program • reinforce and give repeated practice on correct responses ● Move to Criterion III. Require six- to eight-word responses; use the same procedures as under Criterion II. ● Move to Criterion IV. Require spontaneous description of pictures with sentences containing nine or more words; but be flexible about this to promote natural productions. Rosenbek, J. C., LaPointe, L. L., & Wertz, R. T. (1989). Aphasia: A clinical approach. Austin, TX: Pro-Ed.
Promoting Aphasics’ Communicative Effectiveness (PACE). An aphasia treatment program designed to promote face-to-face conversation; developed by G. A. Davis and J. Wilcox; emphasis on exchange of new information, functional communication (as against linguistic precision) with turn taking, free choice for the 37
Aphasia: Specific Programs A client to communicate in any modality; and natural feedback. ● Use a large number of stimulus cards that contain pictured objects, actions, and stories; stack the cards face down on the table ● Take turns drawing cards from the stack; communicate information about the stimulus ● Encourage any mode of expression (words, gestures, drawings, writing, pointing, or a combination of these) ● Add new stimulus cards to promote the exchange of new information ● Provide natural consequences (e.g., ‘‘What did you say?’’ ‘‘Do you mean ?’’ ‘‘I am not sure . . .’’) ● Acknowledge the client’s message while suggesting the correct word or words (e.g., ‘‘I understand. You mean book, right?’’) ● Make variations and adaptations ● Exchange the roles of speaker and listener with the client Davis, G. A. (1993). A survey of adult aphasia (2nd ed.). Englewood Cliffs, NJ: Prentice-Hall. Davis, G. A. (2000). Aphasiology. Boston: Allyn & Bacon.
Response Elaboration Training. A treatment approach that uses a loose training format; designed to expand utterances of aphasic clients; emphasis is on shaping and chaining client- rather than clinician-initiated utterances; allows a wide variety of responses as against a predetermined correct response; developed and researched by K. Kearns and his associates. ● Select line drawings to stimulate speech ● Show a stimulus card and evoke an initial response, any response (e.g., the client may say ‘‘Man . . . sweeping’’ to a line drawing of a person with a broom) ● Reinforce the client; also, shape and model the client’s response (e.g., say, ‘‘Great. The man is sweeping.’’) 38
Aphasia: Specific Programs A ● Ask a wh-question to evoke an elaboration of the
initial utterance (e.g., ask ‘‘Why is he sweeping?’’)
● Reinforce the client’s elaboration and shape and
●
● ● ●
model the initial response combined with the subsequent elaboration (e.g., the client may answer by saying ‘‘wife . . . mad’’ and you say, ‘‘Way to go! The man is sweeping the floor because his wife is mad.’’) Model the longer response a second time and ask the client to ‘‘Try and say the whole thing after me. Say. . . .’’ Ask the client to imitate after a delay if the client is successful at the previous step Continue until the client fails to elaborate any more Introduce another picture for a similar sequence or initiate a different initial response for the same picture

Schuell’s Auditory Stimulation Approach for Aphasia. The method concentrates on intensive auditory stimulation or auditory bombardment; developed by H. Schuell; the method needs more clinical efficacy data. ● Find varied and abundant stimulus materials ● Design a sequence of auditory stimulation ● Work systematically and intensively ● Begin with easy and familiar tasks and increase their complexity; ask the client to: • point to objects named, described, spelled, and so forth • follow directions (simpler to more complex) • answer yes/no questions • respond to alternate items (switch responses) (e.g., ‘‘Show me the horse/Tell me your name.’’) 39
Aphasia: Specific Programs A
● ● ● ● ● ● ●
• repeat words, phrases, and sentences • complete your sentences • answer different kinds of questions • form simple sentences • retell stories • describe pictures and events • engage in conversation • copy and write words Provide intensive auditory stimulation Combine auditory stimulation with visual stimulation Elicit responses to each stimulation, but do not force them Elicit many and varied responses Do not correct responses; instead repeat stimulation Give such feedback as visual charting of progress made in treatment sessions Introduce new materials that contain or extend old materials

Treatment for Wernicke’s Aphasia (TWA). A method of aphasia treatment developed by N. Helm-Estabrooks and P. Fitzpatrick to treat auditory comprehension problems; appropriate for clients with severe Wernicke’s aphasia who can read and understand single picturable words: ● Select a corpus of words printed in lowercase that the client can read aloud and point to pictured stimuli ● Provide a printed word that the client can read, but cannot point to when named ● Ask the client to match the printed word to the picture depicting the word
40
Aphasia: Specific Programs A ● Ask the client to read the word aloud ● Ask the client to repeat the word ‘‘chair’’ as you say
it without showing the picture
● Ask the client to point to the picture of a chair placed
among other pictures
● Introduce new words as the client shows progress ● If new words cannot be introduced by about the
fifth session, reevaluate the procedure; select another procedure ● Chart correct and incorrect responses on a recording sheet Helm-Estabrooks, N., & Albert, M. L. (1991). A manual of aphasia therapy. Austin, TX: Pro-Ed.
Visual Action Therapy (VAT). A nonvocal, visual/ gestural communication approach to the rehabilitation of globally aphasic clients; developed by N. HelmEstabrooks and her associates; neither the clinician nor the client talk during treatment; a client who cannot match an object with the tracing of that object is not a good candidate for VAT; more treatment efficacy data are needed. ● Select seven real objects, shaded line drawings of the objects, and seven action pictures involving the objects ● Select some contextual props (e.g., a screw in a block of wood to use a screwdriver) Level I 1. Matching pictures and objects ● Placing objects on pictures. Place all 7 line drawings of the objects on the table; give each object to the client and gesture to place it on the correct drawing ● Placing pictures on objects. Arrange objects on table, and ask the client to place the picture on the object

Aphonia. Loss of voice; a voice disorder. Apraxia. Disordered volitional movement in the absence of muscle weakness, paralysis, or fatigue; disorder of movement needed to execute learned actions; involuntarily, the same movements may be executed normally; often due to damage to the premotor cortex.
Apraxia of Speech (AOS) in Adults. A neurogenic speech disorder with documented neuropathology in the left cerebral hemisphere including such areas as Broca’s and supplementary motor; also known as verbal apraxia; primarily an articulatory (phonologic) disorder characterized by sensorimotor problems in positioning and sequentially moving muscles for the volitional production of speech; associated with prosodic problems; not caused by muscle weakness or neuromuscular slowness; presumed to be a disorder of motor programming for speech; rare as an isolated disorder; typically associated with Broca’s aphasia.

highly structured, focused on speech production, repetitive, and intensive Do not recommend prosthetic and medical management for AOS as their effects are limited, indirect, and temporary Do not use delayed auditory feedback in treating AOS as data contraindicate it Do not spend time on oral sensation and form recognition exercises in treatment as they are unlikely to result in improved speech production Consider client preference of certain techniques (e.g., some may not like melodic speech or clinician’s manipulation of articulators) Drop techniques that do not produce results or modify them to increase their effectiveness Defer treatment for AOS until treatment for a severe aphasia produces some language production Counsel the client and the family on the nature of apraxia of speech and expected treatment efforts and potential outcomes Start management early Hold frequent treatment sessions Organize sessions to move from easy to difficult tasks End sessions with success Emphasize communicative efficiency and naturalness as you would with most clients in communicative disorders Emphasize articulatory accuracy Select treatment target words that are functional for the client, medical caregivers, and the family
44
AOS: General Procedures A ● Carefully sequence the speech tasks; train:
• automatic speech before spontaneous speech • frequently occurring sounds before less frequently occurring sounds • stimulable sounds before nonstimulable sounds • sounds in word-initial positions before those in other positions • visible before nonvisible sounds • oral-nasal distinctions before voicing distinctions • voicing distinctions before manner distinctions • manner distinctions before place distinctions • bilabial and lingua-alveolar sounds before others • singletons before clusters • high-frequency words before low-frequency words • meaningful words • single-syllable words before multisyllable words • single words before phrases or sentences ● Teach the client self-monitoring skills
Treatment of Apraxia of Speech: General Procedures ● Provide counseling and support for the client and family ● Use consistent and variable practice ● Model sound productions frequently for the patient to
imitate
● Provide systematic practice in producing the target
speech sounds (drill)
● Reduce speech rate initially ● Increase speech rate as articulatory accuracy improves
and stabilizes Use shaping to promote natural prosody Use phonetic placement and Phonetic Derivation Use a variety of sounds and sound combinations Practice sound productions with meaningful material Provide instruction on and demonstration of speech production ● Provide immediate, specific feedback ● ● ● ● ●

• potential need for long-term speech treatment • need to work hard in treatment • coping strategies Encourage the patient to make decisions about the future (returning to work, changing assignments at work, driving, and so forth) Use modeling to promote imitation of carefully selected speech sound contrasts • provide patients with auditory and visual cues • ask the patient to imitate a model • place a single target in varied linguistic contexts (e.g., for the target /t/, a typical list of stimuli might be tea, tie, toe, and two) • ask the patient to contrast the target with other sounds • replace single-syllable words with polysyllabic ones • construct phrases and sentences out of practiced words for more practice • make contrasts harder • use slow rate initially with difficult targets • use varying rhythm and stress (e.g., begin with equal and even stress and progress toward normal) • use multiple contrasts • encourage greater independence Use Contrastive Stress Drills Use Melodic Intonation Therapy (MIT) Use imitation initially Use a question-and-answer dialogue
Use Reading in Treatment
● Ask the client to read aloud ● Fade the printed stimuli by having the client:
• look at the text and talk about it • look at the text and wait before talking about it ● Teach the client to Self-Monitor rate, rhythm, stress, and errors 49
AOS: Treatment of Moderate Forms A Use Gestural Reorganization to Improve Communication ● Explain the need and usefulness of Gestural Reorganization (described under Aphasia; Treatment of Aphasia: Special Techniques or Programs to the client ● Begin with frequently used and simpler gestures (tapping with a finger, drumming with one or more fingers, squeezing the thumb and the index finger, tapping with the foot) ● Model the gesture that works for the client and ask the client to imitate ● Give Manual Guidance (e.g., physical assistance in tapping) if the client needs it ● Tap on the client’s hand if this helps ● Give verbal modeling and other cues as well ● Stabilize the gesture ● Model gestures with speech and ask the patient to imitate both ● Pair gestures with words or phrases initially and pair longer utterances subsequently ● Fade your tapping first ● Fade your verbal modeling ● Use gestures with Contrastive Stress Drills ● Move on to more spontaneous conversational speech ● Fade the client’s gestures if they persist as the client becomes verbally more proficient ● Use a Pacing Board Brookshire, R.

Treatment of Apraxia of Speech: Specific Techniques or Programs Darley, Aronson, and Brown’s Procedure for AOS. A procedure for treating AOS by systematic shaping of articulatory productions and capitalizing on automatic productions. It includes intensive trails for phoneme productions (phonemic drills). ● Shape vowels, consonants, and consonant-vowel (CV) syllables: • identify a vocal response the client can make (perhaps an ‘‘ah’’; if not, a voluntary cough or a hum that can be shaped into a vocal response)
52
AOS: Specific Programs A • have the client repeat the ‘‘ah’’ or any other phonated sound several times, varying its duration and intensity • shape different vowel sounds from the phonated and repeated sound productions (e.g., ‘‘ee,’’ ‘‘oh,’’ ‘‘oo’’) • move to consonants; model /m/ for the client to imitate; give repeated trials • shape syllables out of /m/ (e.g., me, moe, moo) • have the client produce other combinations of consonants and vowels ● Move to automatic responses; have the client: • count to 10 • recite days of the week and months of the year • produce such routine expressions as ‘‘Hello,’’ ‘‘How are you?’’ ‘‘Fine,’’ ‘‘Good morning,’’ ‘‘Thank you,’’ and so forth • sing songs ● Move to intensive practice of phoneme productions (‘‘phonemic drills’’) • produce or hum /m/ and ask the client to imitate it • model CV combinations with initial /m/and ask the client to imitate them (e.g., my, moe, maw, moo, may, me) • model doubled CV combinations and ask the client to imitate each at least 20 times (e.g., my-my) • model consonant-vowel-consonant (CVC) combinations and ask the client to imitate them (e.g., mom, moom, meem); when successful, evoke CVC combinations without modeling • model simple words with initial /m/ and have the client imitate each 10 to 20 times (e.g., man, mine, moon, more); when successful, evoke the words • model two-word phrases, both the words with initial /m/, and have the client imitate them multiple

times (e.g., my mom, miss me, much more); when successful, evoke the phrases model two-word phrases, both the words ending in /m/, and have the client imitate them multiple times (e.g., come home, name him); when successful, evoke the phrases model two-word phrases with /m/ in the initial position of the first word and in the final position of the second and have the client imitate them (e.g., my home, meet them); when successful, evoke the phrases model longer phrases containing multisyllabic words (e.g., moment by moment, Monday morning) introduce other sounds and sound combinations; use essentially the same procedure to create syllables, words, and phrases introduce sentences containing practiced words and phrases

Eight-Step Continuum Treatment for AOS. A procedure for treating AOS developed by J. C. Rosenbek and associates. The main feature of this technique is the systematic shaping of words with the use of cues that are faded out. ● Select the sounds and words for training • select words for initial training that contain easier sounds in them (vowels, nasals, and stops as against fricatives and affricates) • select words that contain sounds produced with closer articulatory contacts for initial training (e.g., words with only bilabial sounds) and increase the distance between the articulatory contact gradually (e.g., words with bilabial and lingua-alveolars moving on to velar sounds)
54
AOS: Specific Programs A • select short, simple, and frequently used words for initial training and increase the length of words gradually ● Apply a sequenced treatment • say ‘‘Watch me’’ and ‘‘Listen to me’’ and then model a target word • ask the client to say the word along with you; this is unison production • say ‘‘Watch me’’ and ‘‘Listen to me’’ and then say the word; ask the client to produce the word aloud as you silently mouth the word • say ‘‘Watch me’’ and ‘‘Listen to me’’ and then say the word; ask the client to produce the word without any cues • say ‘‘Watch me’’ and ‘‘Listen to me’’ and then say the word; ask the client to produce the word several times without any cues • present the target word printed on a card and ask the client to produce it • show the printed target word briefly, remove it, and then ask the client to produce it • ask a question to evoke the target word and let the client respond with it • arrange role-playing conversational situations in which the client has opportunities to produce target words; get family members and others involved in this role-playing Rosenbek, J. C., and associates (1973). A treatment for apraxia of speech in adults. Journal of Speech and Hearing Disorders, 38, 462–472.
Prompts for Restructuring Oral Muscular Targets (PROMPTS). A procedure for treating AOS in children and adults that emphasizes the use of tactilekinesthetic cues in teaching correct production of phonemes; uses manual guidance to position articulators
55
AOS: Specific Programs A or suggest their appropriate movement; developed by P. Square-Store and D. Hayden. ● Note that kinesthetic and tactile cues may be effective only in the context of speech production; by themselves, such cues may be ineffective ● Learn the cues that are described in the cited source; note that cues are given for articulatory positions, voicing, extent of jaw opening, syllable timing, manner of articulation, coarticulation, and so forth ● Learn the many contact positions on the face, neck, jaw, and so forth ● Provide cues by touching the client’s face, neck, jaw, and other structures ● Manually guide the articulators to correct positions ● Model target words for the client to imitate ● Give cues if the imitative production was incorrect ● Manually guide the articulators to correct positions ● Ask the client to produce the sound as the articulators are being moved to correct positions ● Give other cues to suggest articulatory movements that cannot be manually guided Square-Store, P., & Hayden, D.

Voluntary Control of Involuntary Utterances. A procedure for treating AOS, although it was originally developed for clients with severe aphasia with little voluntary speech; based on the assumption that most severely aphasic and apraxic individuals can produce a few words involuntarily and that from such involuntary productions, it is possible to shape voluntary productions; developed by N. Helm and B. Baresi. ● Write down all utterances the client produces during the initial interview and testing situations ● Select words from the client’s involuntary or spontaneous productions 56
AOS: Specific Programs A ● Write down each word the client produced on a sep-
arate sheet of paper
● Present the words one at a time, in the printed
format
● Present some emotionally laden and personally rel-

evant words to see if the client would read them correctly; if so, write them down on separate cards to be used in therapy Discard a word if the client struggles with it or produces neologistic utterance Select a word the client substitutes, but produces correctly, for a word presented (e.g., select the word mother if the client read the printed word father as ‘‘mother’’) Give the selected words, each printed on a separate index card, to the client and ask him or her to practice reading them aloud at home Introduce the selected and printed words, one at a time, during the treatment session; withdraw a word on which struggle appears; reintroduce it later Draw a picture to represent the word on the other side of the card (e.g., a line drawing of a heart to prompt love) Use the picture to evoke confrontation naming by asking ‘‘What is this?’’ Turn the card over and show the printed word if the response is incorrect or the client struggles with it Continue to add new words to the target word list as you observe new word productions Construct phrases and sentences from practiced words and present them to read Ask questions that would evoke responses in which practiced words, phrases, and sentences are likely to be used Use other techniques to expand utterances and correct production of phonemes when a core set of 57

Articulation and Phonological Disorders. Disorders of speech characterized by difficulty in producing speech sounds correctly; sounds may be omitted, distorted, or substituted; difficulty in producing a few sounds with no pattern or derivable rule is often described as an articulation disorder; multiple errors that can be grouped on some principle or characteristics and thus form patterns are typically described as Phonological Disorders. ● Make a thorough assessment of articulation and phonological disorders; consult the sources cited and the PGASLP
Treatment of Articulation and Phonological Disorders: General Guidelines Consider the issues and approaches in treating articulation and phonological disorders: ● Phonetic or phonemic approach? Note that some experts recommend that the clinician decide whether the child needs a motor (phonetic) approach in which single sounds are trained at different levels or a phonemic approach in which errors are grouped and a phonological process (linguistic) approach is used; note also that even in the phonemic approaches, single phonemes must be trained. ● What are the treatment targets? Note that treatment targets may be defined either as the correct production of phonemes in error or the remediation or elimination of phonological process; note also, that either way, individual sounds need to be taught; correct production 58
Articulation: General Guidelines A of all phonemes in conversational speech produced in natural settings is the final treatment target ● How are the targets sounds sequenced? Although all sounds need to be taught, multiple sounds misarticulated cannot be taught all at once; consider selecting certain sounds for initial training, certain others for subsequent training, and the remaining sounds for training during the final stages of therapy: • select sounds that are functional for the child for immediate training; sounds that are important from the standpoint of social and academic performance (e.g., even though /r/ may not be an initial target for all 4year-old children who misarticulate that sound, it may be for a child named Robert Roberson who refers to himself as ‘‘Wobert Woberson’’; in this case, /r/ is functional for the child) • select for immediate training sounds that are stimulable; sounds the child misarticulates in spontaneous speech but imitates correctly when modeled may be more easily taught; hence, select sounds that are imitated correctly for initial training; select sounds not imitated correctly for training in later stages; note that some children may learn equally fast the sounds that are not easily imitated, but shaped in therapy • select for immediate training sounds that are typically misarticulated but correctly produced in some words; use these words as key words to teach correct production of the sounds in other words by using the PairedStimuli Approach described later in this section • select for immediate training sounds that are more visible; visible sounds provide visual feedback when the clinician models them and this might facilitate initial success; select nonvisible sounds for later training • select high frequency sounds for immediate training; teaching correct production of sounds that are more frequently used in speech will improve intelligibility 59
Articulation: General Guidelines A faster and more noticeably than correcting sounds that occur less frequently; see Frequency of Occurrence of English Consonants • select sounds that are normally acquired earlier before selecting those that are acquired later; this recommendation is based on the normative logic that behaviors acquired earlier are easier to teach than those that are acquired later; may not hold true for all sounds that need to be taught • select sounds that the child does not produced at all for immediate training; this recommendation is contrary to the one that suggests inconsistently produced sounds for immediate training; this is based on the assumption that sounds that are totally missing contribute the most to unintelligibility of speech and that teaching them will improve intelligibility the most • select for immediate training sounds whose training may results in generalized production of some untrained sounds; this means that training time and effort can be saved for some sounds; for instance, consider training voiced sounds when voiced and voiceless cognates are both misarticulated to see if unvoiced, untrained sounds will begin to be produced because of generalization; always probe untrained sounds to confirm generalized productions; note that all phonological process approaches assume that some sounds trained within a process is sufficient to have other sounds within it produced without training; note that this may or may not happen ● How is the Response Topography Sequenced? Use the following guidelines in sequencing response topography (levels of response complexity at which the sounds are trained); consider Specific Techniques or Programs described in a later section for somewhat varied recommendations:
60
Articulation: Ethnocultural A • teach the target sounds at the highest level of response complexity that the client can initially handle with success • do not begin teaching at a lower level if the client can handle training at a higher level (e.g., do not train at the syllable level if in the initial treatment trials the client can learn to imitate the modeled productions at the word level) • begin training a sound minimally at the word level; if practical at the phrase level; or even at the sentence level; expect in most cases to begin training at the word level • drop to syllable level only if a the child fails to imitate the modeled production of sounds in words on several trials • drop to the isolated phoneme level only if the child fails to imitate the modeled production of sounds in syllables on several trials • to begin with, experiment with a higher level; you can always drop to a lower level if necessary • move up to a higher level of complexity when training is completed at a lower level (e.g., move on to training the sound in phrases when it has been trained in words) • end training at the level of conversational speech level produced in more naturalistic settings
Ethnocultural Considerations in Treating Articulation and Phonological Disorders ● Note that variables related to ethnic, cultural, and lin-
guistic background of clients significantly affect the assessment, diagnosis, and treatment of articulation disorders; see PGASLP for assessment guidelines of clients with varied ethnocultural background ● Do not recommend treatment for a client who speaks a different dialect of English as all dialects of a language

are its accepted forms with its own cultural heritage; note that this is the official position of the American Speech-Language-Hearing Association on social dialects Note that African American English (AAE) is an accepted form of English; see Treatment of Articulation and Phonological Disorders in African American Children in this section Note that English spoken by a bilingual child is influenced by his or her primary language; thus, there is Spanish-influenced English or Chinese-influenced English; see Treatment of Articulation and Phonological Disorders in Bilingual Children in this section Recommend treatment only if there is an articulation disorder within the dialectal framework of a client’s speech Offer treatment to teach the sound patterns of standard English only if the client’s errors are not due to the influence of a primary language, an accepted social dialect, or African American English Offer treatment to change someone’s otherwise acceptable dialect (such as African American English or Spanish-influenced English) only if the client, the family, or both seek it
A Comprehensive Treatment Program for Articulation and Phonological Disorders ● Assess the client’s articulation and phonological skills;
determine any patterns that may exist (based on distinctive features or phonological processes); consult the cited sources and PGASLP ● Select the target speech sounds for modification; • use previously described criteria for selecting treatment targets (functional targets, sounds that greatly improve intelligibility, sounds that are acquired earlier, sounds that are produced inconsistently, or, alternatively, sounds that are not produced at all) 62

Articulation: A Comprehensive Program A words measured across three consecutive speech samples recorded in the clinic.’’) • at the phrase level (e.g., ‘‘The production of /t/ in word-medial positions at 90% accuracy in a set of 10 two-word training phrases measured across three consecutive speech samples recorded in the clinic.’’) • at the sentence level (e.g., ‘‘The production of /d/ in word-initial positions at 90% accuracy in a set of 10 training sentences measured across three consecutive speech samples recorded in the clinic.’’) • at the conversational speech level (e.g., ‘‘The production of /k/ in word-medial positions at 90% accuracy in three consecutive, spontaneous conversational speech samples recorded in the clinic.’’) ● Write different measurable target objectives for different settings • for the clinical setting (e.g., ‘‘The production of /k/ in word-medial positions at 90% accuracy in three consecutive, spontaneous conversational speech samples produced in the clinic.’’); write similar objectives for other word positions and for phrases and words • for the setting just outside the clinic, but within the clinic premises (e.g., ‘‘The production of /z/ in 10 training phrases at 90% accuracy produced outside the clinic but within the general clinical setting.’’); write similar objectives for other word positions and for words and sentences • for the client’s home setting (e.g., ‘‘The production of /k/ in conversational speech at 90% accuracy in three consecutive samples evoked by parents in their home setting.’’); write similar objectives for other sound targets; note that when the parents do the home training and measurement, the response mode is typically conversational speech; parents are rarely asked to pay attention to position of sounds in words although they can monitor sound productions in words 64

Training criterion: A 90% accurate production of a sound at each level of response complexity (i.e., 90% accuracy in sound production at the word, phrase, and sentence levels evoked on a block of 10 trials; and 90% accuracy in conversational speech with at least 20 productions of the target sound) Probe criterion: A 90% accuracy in the production of sounds in untrained words presented on a series of Probe trials with at least 10 untrained words Probe timing and frequency criterion: A probe will be administered when a child meets the training criterion on four to five stimulus items or exemplars (e.g., when the child’s correct response rate on four words— soup, soap, sun, and seed—reaches 90% accuracy on a block of 10 evoked training trials, a probe will be conducted with at least 10 untrained words interspersed with trained words; the same criterion for all word positions, phrases, and sentences) Reinstatement of training criterion: Treatment on the same sound in the same word position will be reinstated if the probe criterion is not met (similar criterion for phrases and sentences); after training the sound in four new words, a probe will be conducted 67
Articulation: A Comprehensive Program A again; training and probes will be alternated until the probe criterion of 90% accuracy in untrained words is achieved ● Establish Baselines of target sounds in words, phrases, sentences, and conversational speech • measure the correct production of target sounds in conversational speech; use the initial sample recorded during assessment; repeat the procedure to obtain another sample in the first intervention session; if the initial assessment sample and the first interventionsession sample show different percentage of errors for the same sound, repeat the sample • measure the production of target sounds in words with the discrete trial procedure; administer one set of trials with modeling and one without: 1. place a picture or an object in front of the child 2. ask a relevant question (e.g., ‘‘What is this?’’) 3. model the correct response (e.g., ‘‘Say soup.’’); emphasize the target sound 4. wait a few seconds for the child to imitate 5. move the picture toward you and record the sound production as correct, incorrect, or no response 6. present the same picture; ask the same question; but do not model the response; record the response as before 7. administer all target words once with modeling (modeled trial) and once without (evoked trial) 8. calculate percent correct imitated and evoked response rate for each sound and each wordposition ● Teach sound production in words, phrases, and sentences using the discrete trial procedure; initially, train the target sound at the word (or syllable) level with Modeling: 1. describe the target sound and how it is produced; demonstrate its production; and point out its Pho68

5. calculate the percent correct probe response rate based only on the number of probe words, ignoring the trained words in this calculation (e.g., If the child’s production of the target sound was correct in 5 of the 10 probe words, the correct probe response rate is 50%.) ● Alternate between probe and training • if the child’s probe response rate is below 90%, provide additional training with new training words; after training four or six more words, administer another intermixed probe; if the probe criterion is not met, train more words and probe again until the child meets the probe criterion 71
Articulation: A Comprehensive Program A • when the intermixed probe criterion is met, administer a Pure Probe in which only untrained words are presented; calculate the percent correct pure probe response rate; if it is below 90% correct, provide a few additional training trials on all the trained words until the pure probe criterion is met • switch training to another target sound or the same sound in a different word position; follow the same procedure as outlined to complete training the sound at the word initial, medial, and final positions; train other sounds at the word level with the same procedure ● Shift training to higher levels of response complexity • when a sound meets either the intermixed or pure probe criterion for a given word-position (e.g., the initial position), construct two- or three-word phrases that contain a word in which the sound is produced correctly • administer the phrases the same way as the words; model initially; withdraw modeling when at least five correct imitations are produced; reinstate modeling if incorrect responses return; withdraw modeling again • after training four to six phrases to the same training criterion as 90% correct on a block of 10 trials, administer an intermixed probe; provide additional training on new phrases if the intermixed probe criterion is not met; when the intermixed probe criterion is met, administer a probe; when the pure probe criterion is met, shift training to sentence levels in which the word with correct production of the target sound is included • train sentences in the same manner as words and phrases; after presenting the stimulus item, ask a question that would evoke a sentence (e.g., ask ‘‘What is the boy doing?’’ to evoke ‘‘He is having some soup.’’); initially, model the sentences and withdraw 72
Articulation: A Comprehensive Program A modeling: probe generalized production of sounds in conversation in the same way as described for words and phrases • when the pure probe criterion is met for sentences, shift training to conversational speech level; with the help of pictures and other stimulus materials, engage the child in conversational speech and positively reinforce correct productions on an Intermittent Reinforcement Schedule; prompt the correct productions; give corrective feedback • periodically, conduct pure conversational probes in which you engage the child in conversation without reinforcement or corrective feedback; continue training until the child meets the 90% correct production of all target sounds in conversational speech with little or no prompting and reinforcement ● Note that within the framework of this comprehensive treatment program, you can use components of various programs of articulation treatment described under Treatment of Articulation and Phonological Disorders: Specific Techniques or Programs; for instance: • use aspects of the Contrast Approach; in using the Minimal Pair Contrast Method, write minimal pair contrast words for training each sound; for instance, in teaching a child to produce final consonants (elimination of final consonantal deletion), write such word pairs as bow-boat, bee-beet, toe-toad, pie-pine; to teach the correct production of a single phoneme such as /b/ for which the child substitutes /p/, write such pairs as bye-pie, bat-pat, beat-peat, bike-pike; instead of placing a single stimulus item as previously described, place a pair of stimulus items in front of the child; model both the words and ask the child to imitate; withdraw modeling and prove evoked trials; move through response complexity levels as described earlier 73
Articulation: A Comprehensive Program A • use aspects of the Paired-Stimuli Approach; instead of presenting only the target word in which the child misarticulates the sound (as described earlier), present both the target word and a Key Word in which the sound is correctly produced; ask the child to produce the key word first and then the target word; see Paired-Stimuli Approach for details; when the client meets the training criterion for words, move on to probes and then to training the words in sentences • use aspects of the Multiple Phoneme Approach if the child exhibits multiple errors; instead of training one sound at a time as described, train multiple phonemes; see the description of the procedure for details • use aspects of the Phonological Process Approach if the client exhibits multiple misarticulations with identified patterns; note that the phonological process approach does not have a unique treatment procedure; to eliminate a process, individual phonemes still need to be taught; this teaching involves instructions, modeling, phonetic placement, manual guidance, positive reinforcement, corrective feedback, and so forth; in using the phonological process approach, identify patterns or processes in misarticulations; select processes for elimination; teach the phonemes as described in the comprehensive program; when you teach a few phonemes within a process, probe the other phonemes within the process to see if they are now produced on the basis of generalization; if they are, move on to the other processes or to higher levels of response complexity; if they are not produced, train additional sounds within the process ● Implement a maintenance program • Always train the correct production of sounds in sentences and in naturalistic conversational speech during the final stages of treatment 74
Articulation: A Comprehensive Program A • Conduct informal training sessions in Extraclinical Settings; monitor the child’s correct speech sound production outside the therapy room but within the clinic, outside the clinic but in the surround areas, and in such natural settings as the classroom, the shool dining hall, and the library • Train family members, teachers, and peers in reinforcing the correct production of sounds in Natural Settings; ask the parents or other caregivers to observe your treatment session; educate them about the correct production of target sounds; ask them to pay attention to the correct method of providing positive reinforcement and corrective feedback; train them to prompt and promptly reinforce the correct productions at home; train them to hold brief training sessions at home; ask parents to tape-record the session and review the tape to give them feedback • Teach the client Self-Control (Self-Monitoring) techniques to self-manage the correct and incorrect productions; in the treatment sessions, ask the child to judge the accuracy of his or her productions; give feedback on this judgment; ask the child to mark on a sheet his or her own responses as either correct or incorrect; teach the child to pause briefly as soon as an error is produced and then try to produce it correctly • Follow up the child periodically and assess the correct production of phonemes in conversational speech; provide booster treatment when the correct production in conversational speech falls below 90% accuracy Pen˜a-Brooks, A., & Hegde, M.

Treatment of Articulation and Phonological Disorders in African American Children African American English is a product of unique historical and cultural forces; it is a recognized form of English; therefore, note that: ● African American English (AAE) has its own phonologic, syntactic, semantic, and pragmatic rules and conventions ● The phoneme inventory of children speaking AAE will consist of the same phonemes as in Standard American English (SAE); only some phonemes will be used differently, substituted for other phonemes, or omitted in certain contexts ● A majority of phonemes are used in the same way in both AAE and SAE ● The clinician needs to know which AAE phonemic usages that differ from those of SAE are indeed characteristics of AAE; the following phonological patterns are accepted in AAE and hence are not to be treated as disorders: • /l/ lessening or omission (e.g., too’ for tool; a’ways for always) • /r/ lessening or omission (e.g., doah for door; mudah for mother) • /θ/ substitution for /f/ in word final or medial positions (e. g., teef for teeth, nofin’ for nothing) • /t/ substitution for /θ/ in word initial positions (e.g., tink for think) • /d/ substitution for /␦/ in word initial and medial positions (e.g., dis for this and broder for brother) • /v/ substitution for /␦/ at word final positions (e.g., smoov for smooth) • omission of consonants in clusters in word initial and final positions (e.g., thow for throw and des’ for desk)
76
Articulation: African American Children A • consonant substitutions within clusters (e.g., skrike for strike) • unique syllable stress patterns (e.g., gui tar for guitar and Ju ly for July) • modification of verbs ending in /k/ (e.g., li-id for liked and wah-tid for walked) • metathetic productions (e.g., aks for ask) • devoicing of final voiced consonants (e.g., bet for bed and ruk for rug) • deletion of final consonants (ba’ for bad and goo’ for good) • /i/ substitution for /e/ (e.g., pin for pen and tin for ten) • /b/ substitution for /v/ (e.g., balentine for valentine and bes’ for vest) • diphthong reduction or ungliding (e.g., fahnd for find and ol for oil) • /n/ substitution for /g/ (e.g., walkin’ for walking and thin’ for thing) • unstressed syllable deletion (bout for about and member for remember) ● A treatable articulation disorder for a child who speaks AAE is a disorder in the context of AAE, not in the context of SAE ● Note that not all African Americans speak AAE; hence, it should not be stereotypically assumed that AAE articulatory patterns are automatically targets for African American children; family communication patterns and the parents’ preferences will dictate the target phonological patterns ● Plan an articulation and phonological treatment program for an African American child, with the following guidelines: • select the speech patterns of AAE (even if they vary from those of standard English) as treatment goals for a speaker of AAE

• accept and reinforce sound patterns that are accepted in AAE (e.g., a child’s production of baftub for bathtub is acceptable and reinforceable in treatment) • treat first the phoneme usages that are the same in AAE and SAE (many actually are) • treat next the unique phoneme usages of AAE that the child does not use correctly; the goal is to teach what is acceptable in AAE, even if it deviates from SAE • change AAE dialectal patterns to SAE patterns only if the client, the family, or both demand it; in this case, treatment of SAE sound patterns is elective As with all children, select functional speech sounds, child-specific sounds, and sounds that when treated will rapidly improve the child’s speech intelligibility Select stimulus items for treatment from the child’s home environment; consult with parents about pictures, objects, toys, and other materials for their appropriateness and child familiarity Consult the family members about appropriate reinforcers for the child; ask the child about his or her preferences; but as always, determine that a consequence is a reinforcer only after data show that correct productions have increased during treatment Unless data show otherwise, assume that standard treatment procedures (e.g., modeling, phonetic placement, positive reinforcement involving especially verbal praise, and a token system backed up with a variety of culturally appropriate reinforcers) will be effective with African American children; in all treatment sessions, record the response rates systematically to support or correct this assumption

Treatment of Articulation and Phonological Disorders in Bilingual Children Bilingual children are a large and varied group. In the United States, children whose primary language is Spanish constitute a large and growing group. Other groups include children whose primary language is an Asian language or a Native American language. Because of the variety of primary languages that influence the secondary English spoken in the United States, it is not possible to list the characteristics of all the various primary languages that influence American English. Follow the guidelines specified below to develop appropriate articulation and phonological treatment programs for bilingual children: ● Make a thorough assessment of articulation and phonological skills in children who are bilingual; assess in primary language as well as in the secondary Standard American English (SAE); consult the cited sources and the PGASLP ● Analyze errors in the primary language; select these as the treatment targets; note that such treatment requires the working knowledge of the child’s primary language; in the absence of such knowledge, refer the child to a speech-language pathologist (SLP) who has the knowledge ● Analyze errors in SAE that are not due to the influence of the primary language; these errors, too, may be treatment targets; note that a monolingual English-speaking SLP can offer this treatment, assuming that an assessment was made with the help of a bilingual clinician ● Analyze English sound productions that vary from those in SAE but are due to the influence of the child’s 79

primary language; these are not normally the targets of articulation treatment Treat SAE articulatory variations in English only if the client or the family request such treatment because of the advantage SAE offers in educational, social, and occupational settings Treat errors in phonemes that are common to the child’s primary language and the secondary SAE on a priority basis As with all children, select functional speech sounds, child-specific sounds, and sounds that when treated will rapidly improve the child’s speech intelligibility Select stimulus items for treatment from the child’s home environment; consult with parents about pictures, objects, toys, and other materials for their appropriateness and child familiarity Consult the family members about appropriate reinforcers for the child; ask the child about his or her preferences; but, as always, determine that a consequence is a reinforcer only after data show that correct productions have increased during treatment Unless data show otherwise, assume that standard treatment procedures (e.g., modeling, phonetic placement, positive reinforcement involving especially verbal praise, and a token system backed up with a variety of culturally appropriate reinforcers) will be effective with bilingual children; in all treatment sessions, record the response rates systematically to support or correct this assumption Modify treatment techniques to suit the individual child; keep good records of such modifications to evaluate whether they were needed because of individual differences or ethnocultural variations Refer the child to a bilingual clinician who knows the child’s primary language
80
Articulation: Bilingual Children A ● Use the following characteristics of Spanish-influenced
English in treating articulation and phonological disorders in a child whose primary language is Spanish: • Spanish has only 5 vowels (as against 15 in English) • the English consonants /v/, /θ/, /␦/, /z/, and // are not in Spanish; while speaking English, some of these may be produced as allophonic variations of phonemes present in Spanish • some Spanish consonants, though similar to certain consonants in English, may be produced differently • Spanish has only a few consonants in word final positions (only /s/, /n/, /r/, /l/, and /d/) • Spanish consonantal clusters are fewer and simpler; the /s/ cluster, most common in English, does not occur in Spanish; final clusters are rare in Spanish • English /t/, /d/, and /n/ tend to be dentalized • final consonants may be devoiced (e.g, dose for doze) • /b/ may be substituted for /v/ (e.g., bery for very) • weak or deaspirated stops, giving the impression of omission of stop sounds • /tʃ/ may be substituted for /ʃ/ (e.g., Chirley for Shirley) • /d/ or /z/ may be substituted for /␦/, which does not exist in Spanish (e.g., dis for this or zat for that) • schwa may be inserted before word-initial consonant clusters (eskate for skate or espend for spend) • omission of many consonants at word-final positions • /r/ may be trapped (as in the English word butter) or trilled • word-initial /h/ may be silent (e.g., old for hold or it for hit) • /y/ may be substituted for /d/, an absent sound in Spanish (e.g., yulie for Julie) • /s/ may be produced more frontally, giving the impression of a lisp
81
Articulation: Sound-Evoking Techniques A ● In treating articulation and phonological disorders in
other bilingual children (such as those whose primary language is one of many Asian languages): • use the general guidelines already specified for working with bilingual children • note that because of the diversity of Asian languages, a general description of phonological characteristics is neither practical nor meaningful • note that many descriptions in the literature under the heading of Asian children or speakers apply only to the Chinese, not to other Asian languages • note that Asian languages belong to different language families and hence are highly varied in their phonological and other characteristics Kayser, H.

Sound-Evoking Techniques for English Consonants. Several procedures to evoke sounds during treatment are available; no systematic research has evaluated the relative effectiveness of these procedures; these techniques are based on clinical experience of many clinicians; therefore, use them with caution and modify or abandon procedures that do not produce results; generously reinforce any slight improvement in the client’s target sound production or a movement in the right direction: ● Evocation of /p/, a bilabial, voiceless, stop-plosive: • model the sound production several times; draw attention to the lip closure, building up of air pressure in the mouth, and air explosion as the sound is produced 82

• with a piece of paper, show the plosive characteristic that can move the paper held in front of the mouth • manually guide the two lips to the required articulatory posture; ask the child to forcefully expel the air from the mouth • shape the /p/ from the explosive airstream Evocation of /b/, a bilabial, voiced stop-plosive: • use the same procedures as those described for /p/ except that, as the child forcefully releases the air, ask him or her to add voice or to turn on the voice box; let the child feel the vocal fold vibrations as you produce the sound; ask the child to produce those vibrations as the air is released from the mouth; shape the /b/ out of these manipulations Evocation of /t/, a lingua-alveolar, voiceless stopplosive: • model the sound production several times, drawing attention to the placement of the tongue tip against the alveolar ridge; with the help of a moving feather, draw attention to the air that escapes through the mouth as the sound is produced • ask the child to place the tongue tip firmly against the alveolar ridge; if necessary, place a piece of food on the alveolar ridge with a Q-tip to teach the exact tongue tip placement; hold the breath briefly, lower the tip slightly, and release the air as the tongue tip is lowered • shape /t/ with such manipulations Evocation of /d/, a lingua-alveolar, voiced stop-plosive: • use the same procedures as those described for /t/; in addition, teach the child to add voicing by helping the child feel the vocal fold vibrations; ask the child to turn on the voice box Evocation of /k/, a lingua-velar, voiceless stop-plosive: • model the sound production several times, demonstrate the tongue tip placement behind the front teeth 83

and the raised back portion of the tongue that makes firm contact with the soft palate; build up air pressure in the mouth and suddenly lower the back of the mouth to release the air in a plosive manner • shape the sound with this manipulation Evocation of /g/, a lingua-velar, voiced stop-plosive: • use the same procedure as described for /k/ and ask the child to add voice or turn on the voice; let the child feel the vocal fold vibrations Evocation of /f/, a labiodental, voiceless fricative: • model the production of the sound several times; draw attention to the lower lip position under the front upper teeth; manually guide the lips and the teeth to the right placement • ask the child to blow air through the teeth and the lip when they are still in contact with each other; ask the child to turn off the voice box • use a feather or a piece of paper to demonstrate the air flow out of the mouth • shape the sound out of such manipulations Evocation of /v/, a labiodental, voiced fricative: • use the same procedure as described for /f/ and ask the child to add voice or turn on the voice box; let the child feel the vocal fold vibrations Evocation of /θ/, linguadental voiceless fricative: • model the sound production several times; draw attention to the slightly protruded tongue tip between the upper and lower front teeth and the air being blown over the tongue and through the constriction between the tongue tip and the teeth • instruct the child to position the tongue as demonstrated; if necessary, ask the child to stick the tongue out of the mouth, then draw it slowly in until it is correctly positioned; use manual guidance with a tongue depressor

Treatment of Articulation and Phonological Disorders: Specific Techniques or Programs Behavioral Approaches. Articulation treatment techniques based on the use of Behavioral Contingencies of stimulus-response-consequence in shaping or teaching sound production in words, sentences, and conversational speech; also may use a programmed learning approach; elements of behavioral approaches are found in almost all programs of articulation and phonological treatment, including those that that are not typically described as behavioral. Programmed Conditioning for Articulation. A behavioral treatment method that uses behavioral principles and programmed learning concepts; developed by R. Baker and B. Ryan. ● Criterion of Performance: Ten correct responses in a row.

Contrast Approach. A cognitive-linguistic approach to treatment of articulation disorders; often used in remediating phonological processes; uses contrasting pairs of words that contain minimal or maximal differences between the target sounds and those contrasted; the actual training of sounds may involve behavioral contingencies; researched by multiple investigators. Minimal Pair Contrast Method. Uses word pairs that have minimal phonemic contrast (e.g., bat-pat). ● Analyze the client’s misarticulations ● Write minimal contrast word pairs; for instance, to remediate deletion of final consonants, write such pairs as boat-bow, bee-bead, and tee-teeth; to remediate 91
Articulation: Specific Programs A fronting, write such pairs as can-tan, key-tea, and gate-date. ● Obtain pictures for words in selected pairs ● Begin treatment by modeling both the target and the contrast words; ask the child to imitate both ● Provide extensive trials on imitative production of the target and contrast words ● Ask the client to spontaneously name the picture pairs ● Ask the client to name the pictures and then sort them into separate piles ● Alternatively, ask the client to say the target word as you pick the correct picture (the client says boat and you pick up the picture of boat; if the client says bow, you pick-up the picture of bow and then correct the client) ● Ask the client to match two pictures by first picking a picture from several displayed and then selecting its minimal pair match Maximal Pair Contrast Method. Uses word pairs that have multiple (maximal) phonemic contrasts or maximal opposition. ● Select word pairs that contrast maximally; for instance, select such word pairs as chain-main; canman; gear-fear (the initial phoneme in the first word of each pair is the target of treatment; the initial phoneme in the second word in each pair is the phoneme with maximal opposition) ● Use the general procedure outlined for Minimal Pair Contrast Method Cycles Approach. A phonological pattern approach designed to treat children with multiple misarticulations and highly unintelligible speech; approach consists of treatment cycles which vary between 5 weeks and 16 weeks; includes auditory stimulation and production practices; developed by B. Hodson and E. Paden.

Distinctive Feature Approach. Articulation treatment approach based on a distinctive feature analysis; the goal is to establish missing Distinctive Features or feature contrasts by teaching relevant sounds; technically, not a treatment procedure; approach assumes that teaching a feature in the context of a few sounds will result in generalized production of other sounds with the same feature or features; more research is needed to fully support this assumption; approach is most useful with children who have multiple misarticulations that can be grouped on the basis of distinctive features, not useful for (a) treating distorted sounds as the analysis is not relevant to such errors; (b) treating a client with only a few errors that do not form patterns based on distinctive features; developed and researched by multiple investigators. ● Obtain an extended conversational speech sample 94

Multiple Phoneme Approach. A method of articulation remediation in which all errors are treated in all sessions; appropriate for children with six or more errors; based on behavioral principles; focuses on sound production in conversational speech; does not emphasize auditory discrimination training; consists of establishment, transfer, and maintenance phases; each phase has several steps; highly structured and carefully sequenced; developed and researched by R. McCabe and D. Bradley. ● Obtain conversational speech sample of about 150 words ● Mark each word that contains at least one error ● Calculate percentage of words spoken correctly (Whole Word Accuracy: WWA) ● Use WWA measure to supplement single-word articulation tests Phase I, Step 1. Establishment. Goal: Production of consonants in response to a printed letter or phonetic symbol representing it. ● Show an upper- or lowercase letter and ask ‘‘Do you know what sound this letter makes?’’ (visual cue only) • Ask the client to produce the sound in isolation on five successive trials (record the correct responses) • If the client cannot do this, record the error and move to the next step ● Give verbal instructions along with auditory and tactile stimuli; use any other effective procedure (auditory, visual, and phonetic-placement); continue until four out of five attempts are correct; move to the next step
96
Articulation: Specific Programs A ● Show the letter and model the sound for the child
to imitate (auditory and visual stimuli only); seek five consecutively correct responses; then, move to the next step ● Present only the letter (visual stimulus only); ask the client to make the sound; seek five consecutively correct responses (Skip visual only step for children under age 5) ● In the first session or two, include sounds produced correctly to give experience of success; omit these sounds in subsequent sessions ● Reinforce correct responses (verbal praise, tokens) Phase I, Step 2. Holding Procedure. Designed to maintain the correct production of sounds produced in isolation when they are not yet advanced to syllable or word levels; other sounds are moved to these higher levels. ● Evoke one correct response by showing the letter once and asking the client to produce the sound (visual stimulus only) Phase II. Transfer. Goal: Production of all target sounds in conversational speech; simultaneous training of five or more sounds; sounds may be at different levels. Phase II, Step 1: Syllable. Used only when the client fails to produce the sound correctly in 6 out of 10 probe words (5 words with the sound in the initial position and 5 words with the sound in the final position) ● Provide one auditory-visual model or one visualonly stimulus ● Ask the client to produce the sound with a variety of vowels ● Ask the client to produce the sound in both initial and final positions
97
Articulation: Specific Programs A ● Seek five productions for each stimulus pre-
sentation
● Use a criterion of 80% correct over two sessions
or 90% correct in one session Phase II, Step 2: Word. Goal: Accurate production of target sounds in 25 to 30 varied words to be later included in sentences (nouns, verbs, modifiers, and prepositions). ● Present printed words or picture stimuli ● Ask the client to produce the word ● Accept erred production of nontarget phonemes ● Move training to the sentence level when the sound in a given position (e.g., initial position) is produced with 80% accuracy over two sessions or 90% accuracy in one session ● Continue training at the word level when the sound in a given position (e.g., final position) does not meet the criterion ● Consider using another approach, such as the minimal contrast therapy or phonological process approach, to eliminate the final consonant deletion process Phase II, Step 3: Phrase and Sentence. Goal: Correct production of all sounds in words; self-monitoring. ● Construct phrases and sentences (imperatives, declaratives, and interrogatives) with words already trained, adding new words as needed ● Present Rebuses, Blissymbolics, or pictures for nonreaders ● Model phrases and sentences ● Ask the client to imitate ● Note phonetic contexts in which errors occur; have the client practice the production in these contexts ● Have the client practice words in which sounds are produced incorrectly as well as those that precede or follow such words 98
Articulation: Specific Programs A ● Vary stress, rhythm, timing, and accent patterns ● Seek 80% accuracy over two sessions or 90% ac-
curacy in one session, calculating accuracy with target sounds only Phase II. Step 4: Reading and Storytelling. Goal: Accurate production of target sounds in connected utterances containing four to six words. ● Select reading materials that are easy for the child ● For nonreaders, select comic books, picture books, and sequence cards ● Tell a story and ask the child to retell it ● Seek whole word accuracy and 80% correct production over two sessions or 90% in one session Phase II. Step 5: Conversation. Goal: Accurate production of all sounds used in conversational speech. ● Begin to monitor conversational speech when even one or two sounds reach this level ● Encourage discussions, descriptions, comments, questions, state facts, identify cause-effect relations, talk about emotions and desires; do not just answer questions ● When multiple sounds need to be monitored, group sounds on the basis of manner or place of articulation; monitor sounds in one group for 3 to 5 minutes; then, monitor sounds in another group, and so on ● Count every spoken word as a response and calculate the whole word accuracy level ● Note the context in which certain sounds are misarticulated and use these contexts for additional practice ● Seek 80% correct production of all words over two sessions or 90% in one session for children 6 years and older; seek 69% criterion for younger children 99
Articulation: Specific Programs A Phase III: Maintenance. Goal: Maintenance of 90% whole word accuracy in conversational speech produced in various speaking situations without treatment or external monitoring. ● Have the client return to the clinic; assess and monitor sound productions ● Visit classrooms ● Maintain telephone contact with the client and the family ● Obtain reports from others ● Have others monitor accuracy in various speaking situations ● Monitor for 3 months McCabe, R., & Bradley, D.

Paired-Stimuli Approach. A method of articulation remediation that depends on identifying a Key Word in which a target sound appears only once in either initial or final position and is correctly produced 9 out of 10 times; uses key words to teach the production of sounds in other contexts; explicitly uses operant reinforcement contingencies; uses pictures to evoke the target words; highly structured and carefully sequenced; a single speech sound is the target at any one time; developed and researched by J. Irwin and A. Weston. Word Level Consult Weston and Irwin(1971/1975) for assigned key words, questions to be asked, and expected answers. ● Select the target phonemes for the client

sound in the initial position and two containing it in the final position When absent, create key words by teaching them Select at least 10 training words in which the target sound is misarticulated and the sound appears only once in the same position as in the key word Select pictures as stimuli to evoke the word productions Place the first key word (picture) with sound in the initial position in the center and arrange the 10 training words (pictures) around it Point to the key word (picture) and ask the client to, ‘‘Say this’’ Reinforce the likely correct production Ask the client to name one of the 10 target words Ask the child to name the key word again Ask the child to name another target word; alternate the key word and a training word in this manner Reinforce the client by giving a token for the correct production of the target sound in both the key and the training words; ignore misarticulations of other sounds Complete a training string by pairing each of the 10 target words with the key word Include three training strings in each session that lasts about 30 minutes Adhere to a training criterion of 8 correct out of 10 productions of the training words in two successive training strings without reinforcement Arrange the second key word with the same sound in the final position and pair it with 10 training words
101
Articulation: Specific Programs A ● In the next stage of training, ask the child to say
the third key word with the target sound in the initial position and a training word as a Response Unit with only a brief pause between the two (e.g., ‘‘said-salad’’; s is the target; said is the key word and salad is the target word) ● Reinforce only if the sounds in both the words are correctly produced ● Adhere to a training criterion of 8 out of 10 correct response units over two successive training strings ● Ask the child to say the fourth key word with the target sound in the final position and a training word as a response unit with only a brief pause between the two ● Reinforce the correct productions in response units as before Sentence Level ● Pair the first key word with its 10 training words; ask a question designed to evoke a response in the sentence form (e.g., ‘‘What do you see?’’ ‘‘I see a cat’’ with see as the key word for /s/). ● Reinforce with a token on a fixed ratio 3 (FR3) schedule of reinforcement ● Complete a training string of 10 questions ● Adhere to the training criterion of 8 out of 10 correct sentences over two training strings ● Alternately, ask two questions (e.g., ‘‘What do you see?’’ for key word see and ‘‘That’s what?’’ for key word that’s) as you present the first and the second key words and their 10 training words ● Reinforce with a token for three correct sentences (FR3) ● Adhere to the training criterion of 8 out of 10 correct sentences over two training strings
102
Articulation: Specific Programs A ● Ask four questions (e.g., ‘‘What is this?’’ ‘‘What
do you see?’’ ‘‘That’s what?’’ and ‘‘What did you say that was?’’) as you present the first and the fourth key words and their 10 training words ● Adhere to the criterion of 8 out of 10 correct sentences over two successive training strings Conversational Level ● Engage the child in conversation ● Stop the conversation (a) when the child correctly produces a target sound in four words or (b) when the child incorrectly produces a target sound in any word; model the correct production; ask the child to repeat it ● Reinforce the child verbally and by showing your scoring of correct responses ● Subsequently, require the correct production of a target sound in seven words; probe when the child can do this ● In subsequent stages, require the correct production of a target sound in 10 and 13 words: probe when the child can do this ● Give verbal praise and visual feedback of scoring only when all productions are correct ● For all probes, take a conversational speech sample; no feedback of any sort during probes ● Terminate training on a given sound when the child gives 15 consecutively correct productions of a target sound in conversation held on two successive treatment sessions separated by at least 1 day Irwin, J.

Phonological Knowledge Approach. An approach to treating phonological disorders in children; based on the assumption that children’s knowledge of phonological rules of the adult system is reflected in their productions; the greater the consistency of correct productions in varied contexts, the higher the level of phonological knowledge and vice versa; treatment begins with sounds that reflect least knowledge and ends with those that reflect greater degrees of knowledge; proposed by M. Elbert and J. Gierut and researched by Gierut and associates. ● Obtain a representative, continuous, conversational speech sample • sample all sounds • sample sounds in all word positions • sample each sound in several different words • sample each word more than once • sample production of minimal pairs (cat/bat) • sample morphophonemic alterations (dog/doggie; run/running) ● Analyze the sample • create the child’s phonetic inventory (all the sounds the child produces, correctly or incorrectly) • create the child’s phonemic inventory (sounds the child uses contrastingly or those that signal meaning) • find out the distribution of sounds (distribution by word position and by morphemes) • create hierarchical arrangement of sound productions that reflect least knowledge (misarticulations in all word positions and in all morphemes) to most knowledge (no misarticulations) ● Treat the sounds that reflect the least knowledge first and move up through the hierarchy 104
Articulation: Specific Programs A ● Use the Contrast Approach (described earlier in this
section) in teaching sounds • use near-minimal pairs (words that differ by more than one sound) if necessary and initially • move from imitation to spontaneous productions • reinforce the child for correct productions • in spontaneous production training, ask the child to name and sort pictures into target and contrast piles (sorting) • present an array of pictures and ask the child to select a picture, name it, and find its minimal pair match (matching) ● Promote generalization and maintenance by varying the context of sound productions, selecting childspecific stimulus items, loosely structuring treatment in later stages, and so forth Elbert, M., & Gierut, J. (1986). Handbook of clinical phonology. San Diego: College-Hill Press.
Phonological Process Approach. An approach to treating articulation disorders; technically, not a treatment procedure because it does not involve any unique treatment techniques; an approach to treatment based on the assumptions that multiple errors reflect the operation of certain phonological rules and that the problem is essentially phonemic, not phonetic; group errors based on Phonological Processes; targets the elimination of processes by teaching only a few individual phonemes within a process on the assumption that other, untreated phonemes within the same process will be produced without training—an assumption with mixed evidence; untrained phonemes may or may not be produced; uses several established methods of teaching sounds; researched by multiple investigators; includes multiple programs with varying degrees of empirical research, some with negligible controlled research base; the Cycles Approach and the 105
Articulation: Specific Programs A Phonological Knowledge Approach are examples of phonological process approaches to treatment. ● Obtain a conversational speech sample that reflects a variety of words and linguistic contexts in which all sounds are produced; may use one of the several available protocols of phonological analysis ● Identify the Phonological Processes that account for error patterns ● Select processes for elimination through teaching specific sounds or groups of sounds; for instance: • identify all phonemes that are misarticulated within a process (e.g., all final consonants a child omits—the final consonant deletion process) • teach only a few final consonants • use any effective procedure to teach the consonants • use the comprehensive treatment approach described at the beginning of this main entry with modeling, shaping, manual guidance (phonetic placement), positive reinforcement and corrective feedback • alternatively, use paired-stimuli approach, contrast approach, or any other technique supported by controlled evidence • teach sounds in syllables, words, phrases, and sentences ● When a few final consonant productions meet the training criterion, probe to see if other, untreated sounds within the pattern are produced correctly without training, based on generalization (e.g., other untreated final consonants that are omitted) ● If there is no generalized production of untreated phonemes, then treat them as well ● If untreated phonemes are produced on the basis of generalization, select another phonological process for elimination; teach selected phonemes within the process; administer probes 106
Articulation: Specific Programs A ● Schedule maintenance activities as appropriate

Sensory-Motor Approach. An articulation treatment approach based on the assumption that syllable is the basic unit of training; requires a context in which a misarticulated sound is correctly produced; focuses on increasing auditory, tactile, and proprioceptive awareness of motor patterns involved in speech sound production; does not include auditory discrimination training nor training at the sound level; developed and researched by E. McDonald. ● For each target sound, find a context in which the child produces it correctly ● If necessary, administer a deep test such as McDonald’s Deep Test of Articulation to find a context in which an otherwise misarticulated sound is correctly produced (e.g., in the context of watch-sun, a child who generally misarticulates the /s/ may produce it correctly) Practice With Sounds Produced Correctly ● Select a sound the child can produce correctly and combine it with vowels to create duplicated bisyllables (kiki, koko, kaka, kuku, etc.) ● Begin treatment by having the child imitate your production of the bisyllables; place equal stress on both the syllables ● Next, have the child imitate your production of bisyllables with primary stress on the first syllable ● Then, have the child imitate your production of bisyllables with primary stress on the second syllable ● Ask the child to describe the placement of the articulators and the direction of the articulatory movements 107
Articulation: Specific Programs A ● Change the vowel and have the child imitate bi-
syllables with the same consonant but different vowels (e.g., moving from kiki to koko); provide training such that a variety of articulatory movements are practiced for a given sound ● Give similar training with other consonants the child produces correctly ● Initiate training on trisyllables (e.g., kukuku or lalala); follow the procedure used to train bisyllables Training Correct Production of Misarticulated Sounds. Begin training on the typically misarticulated sound with a context in which it is correctly produced (e.g., /s/ is produced correctly in the context of watch-sun, a deep test item) In successive stages, ask the child to say watch-sun: ● with slow motion ● with equal stress on both the syllables ● with primary stress on the first syllable ● with primary stress on the second syllable ● and prolong the /s/ until a signal is given to complete the word ● in sentences (‘‘Watch, the sun will burn you.’’) ● in other and longer sentences and with different stress patterns ● use such a performance criterion as 20 consecutively correct productions to move from one level to the next Next, vary the phonetic contexts (e.g., watch-sit, watch-saw) ● have the child practice correct production of the target sound in different phonetic contexts by varying the words in which the target sound appears) ● have the child practice correct production in the context of different first words (e.g., teach-sand, reach-soon)
108
Articulation: Specific Programs A ● have the child practice the target sound in a to-
tally different phonetic context (e.g., mop-sun or book-sun) ● implement generalization and maintenance activities McDonald, E. T. (1964).

Traditional Approach. An articulation treatment approach developed for the most part by Van Riper who included several techniques from various sources; sounds are trained in isolation, in syllables, in words, and in sentences; training includes four levels: (1) Perceptual Training or Ear Training; (2) Production Training: establishment; (3) production training: stabilizing the productions; and (4) production training: transferring the productions; used or researched by multiple investigators. Perceptual Training (Ear Training) ● Demonstrate how the target sound is produced ● Ask the child to raise a hand when he or she hears the sound in isolation among sounds that are similar and among sounds that are dissimilar ● Ask the child to raise a hand when he or she hears the target sound in first words, then phrases, and finally in sentences ● Ask the child to identify the position of the sound in words (initial, medial, or final) ● Bombard the client with productions of the target sound ● Have the child judge your correct and incorrect productions of a target sound
109
Articulation: Specific Programs A Production Training Sound Establishment ● Ask the child to imitate your correct productions of target sounds in isolation, in syllables, or in words ● Vary the phonetic contexts of such productions ● Use contexts in which the target sound is correctly produced ● Use such techniques as Phonetic Placement, Moto-Kinesthetic Method, and Shaping to teach the sound production Stabilization ● Continue training the sound in isolation to encourage more consistent production ● Vary the number and intensity of productions ● Switch from one sound to the other ● Ask the child to respond to printed letters that represent the target sounds ● Have the child produce the sounds in nonsense syllables or clusters ● Begin training the sounds in words when the sounds are consistently produced correctly in nonsense syllables ● Move from simple to complex words; continue training until the sound productions are stabilized in a variety of words and in each word position (initial, medial, and final) ● Train at the phrase level if necessary ● Move to sentences; vary the sentence lengths; move from simpler and shorter to more complex and longer sentences and from those with single occurrence of the target sound to those with multiple occurrences ● Have the child produce sentences along with you in slow motion and at rapid rate
110
Artificial Larynx A ● Begin training at the conversational level when
the child can fluently and easily produce the target sounds in sentences ● Structure the conversation initially to maximize opportunities for the production of target sounds ● Move to spontaneous conversational speech ● Have the child read to further stabilize sound productions Transfer (Carry-over) ● Initiate carry-over activities when the child can produce the sounds correctly in unstructured conversational speech ● Give specific speech assignments for the child to complete at home ● Require reports from parents on assignments ● Teach self-monitoring ● Create varied speaking situations for the client to use the target sounds Pen˜a-Brooks, A., & Hegde, M.

Speech correction: An introduction to speech pathology and audiology (7th ed.). Englewood Cliffs, NJ: Prentice-Hall.
Artificial Larynx. Mechanical larynges used in the communicative rehabilitation of patients with laryngectomy; generates a mechanical sound that is articulated into speech with people whose larynges have been removed because of such life-threatening diseases as cancer; the same as Electronic Device for Alaryngeal Speech or Pneumatic Device for Alaryngeal Speech.
Aspiration. A condition in which food, fluid, and secretion penetrate below the true vocal folds; can cause asphyxiation and aspiration pneumonia; potential complications in patients with Dysphagia.
111
Aspiration Pneumonia A Aspiration Pneumonia. Lung infection due to aspiration; a complication often found in patients with Dysphagia.
Assessment. Procedures that include (a) description of a client’s existing and nonexisting communicative behaviors, background variables, and associated factors to evaluate or diagnose a communicative problem; (b) clinical measurement of a person’s communicative behaviors. ● Obtain case history ● Interview client, the caregivers, family members, and others concerned ● Conduct an orofacial examination ● Make client-specific judgments on use of standardized or nonstandardized measures ● Use measures appropriate to the client and his or her ethnic, cultural, and linguistic background ● Screen hearing ● Obtain a speech-language sample ● Analyze results ● Draw conclusions; make a diagnosis; recommend treatment; disseminate information to the client, the family, and the referring professional ● Consult books on assessment in speech-language pathology and PGASLP
Assimilation Processes. A group of Phonological Processes in which the productions of dissimilar phonemes sound more alike; in phonological treatment, the objective is to eliminate such processes; major assimilation processes include: ● Alveolar assimilation: substitution of an alveolar sound by a nonalveolar sound (e.g., substitution of /d/ for /p/) ● Devoicing: substitution of a voiceless final sound for a voiced (e.g., /k/ for /g/ in final positions) ● Devoicing of final consonants: substitution of a voiceless final consonant for a voiced (e.g., /t/ for /d/) ● Labial assimilation: substitution of a labial sound for a nonlabial (e.g., /b/ for /d/) 112
Assimilative Nasality A ● Nasal assimilation: substitution of a nasal consonant for a
nonnasal (e.g., /n/ for /d/)
● Postvocalic voicing: substitution of a voiceless sound for a
voiced sound that follows a vowel (e.g., /t/ for /d/)
● Prevocalic voicing: substitution of a voiced sound for
voiceless sound preceding a vowel (e.g., /b/ for /p/ in prevocalic positions) ● Reduplication: repetition of a syllable, resulting in substitution of one for another (e.g., wawa for water) ● Velar assimilation: substitution of a velar consonant for a nonvelar (e.g., /g/ for /d/)
Assimilative Nasality. Undesirable nasal resonance on vowels that are adjacent to nasal consonants.
Assistive Listening Devices. Devices other than the traditional hearing aids that help persons with hearing impairment in various communicative situations; used in situations in which the traditional hearing aids are less effective; most capable of transmitting speech signals directly from the mouth of the speaker to the ears of the listener; see also Aural Rehabilitation; include the following: ● Frequency Modulated (FM) auditory trainers that offer wireless connection between a speaker and a listener; consists of a transmitter with a microphone and a receiver with earphones; signal is transmitted to the receiver through radio frequency and is unaffected by noise in the room, a problem not solved by traditional hearing aids; may be used in group aural rehabilitation ● Infrared listening systems that include transmitters that send messages on pulses of light and receivers worn by individuals to receive and decode those messages; useful in large listening environments such as concert halls, theaters, houses of worship, and classrooms. ● Signaling or alerting devices (also known as environmental adaptations) that include mechanisms to amplify telephone ringing; flashing lights that alert a person with 113
Ataxia A hearing impairment to incoming phone calls, smoke or fire alarm, a baby’s cry, ringing of a door bell, and so forth; vibratory mechanism that wakes up a person with hearing impairment from sleep ● Television or radio amplifiers that include a small amplifier, a microphone that is clipped to the television or radio, and ear phones the person needing extra amplification of signals wears; volume may be adjusted on the amplifier, thus allowing louder signals only for the person using the system ● Text telephones (TTs) and telecommunication devices for the deaf (TDDs) that allow two persons communicating over a phone to type their messages; allows display of typed messages on a small screen on the telephone; may be a part of a relay service that allows a hearing person without the special equipment to speak to a staff person who types in the message, which is transmitted to the TT used by the person with hearing impairment
Ataxia. A neurological disorder characterized by disturbed balance and movement due to injury to the cerebellum.
Ataxic Dysarthria. A type of motor speech disorder resulting from damage to the cerebellum. See Treatment of Dysarthria: Specific Types under Dysarthria.
Athetosis.
A neurological disorder characterized by slow, writhing, worm-like movements due to injury to the extrapyramidal motor pathways.
Atrophy. Wasting away of tissues or organs. Attention Disorders. Disorders that affect a person’s reaction to stimuli in the environment; disorder that affects the duration of response to stimuli; attention is a prerequisite for all kinds of learning; disturbed attention makes learning difficult or impossible; compounds memory deficits; often found in persons with neurological disease or trauma; 114
Attention Disorders A attention is a treatment target for patients with aphasia, dementia, traumatic brain injury, mental retardation, autism, and similar disorders. ● Make a thorough assessment of attentional deficits; consult the cited sources and the PGASLP ● Integrate attentional training activities to other functional activities such as communication training ● Work directly on functional attentional tasks (e.g., paying attention to speech or instructions; to environmental cues; to treatment stimuli) instead of abstract and nonfunctional attentional tasks (e.g., showing a bunch of playing cards and asking the patient to indicate when a red card is shown; such mental exercises as counting backwards; listening to auditory clicks and signaling when there is a shift in the pattern of clicks) ● Consult with the family and health care staff in identifying attentional deficits of concern and functional treatment activities and goals ● Design a treatment program that is client-specific, functional, and helps pay attention to environmental events; as a speech-language pathologist, consider strategies to improve the patient’s attention in all treatment tasks ● Work with the family and health care staff to ensure that they, too, use the same strategies as you do ● Select treatment stimuli that are relevant to the patient’s interests and premorbid hobbies; prepare colorful and attention-getting stimuli for treatment ● Implement the treatment initially in a quiet, simple, clutterfree place with minimal stimuli; gradually broaden the treatment environment to include more natural settings in which you reinforce attentional behaviors ● Conduct treatment sessions sitting in front of the client; make sure there is enough lighting on your face and on the treatment stimuli and activities ● Give all treatment instructions in simple, brief, and direct language; repeat, if necessary; break down the instructions 115

to smaller steps; talk slowly; and make sure the patient understands your instructions by asking questions about them Draw the patient’s attention before presenting all treatment stimuli by giving alerting signals and frequently using his or her name (e.g., ‘‘Watch for this now, Mr. Triumph’’; ‘‘Here it comes, Mrs. Robinson’’; ‘‘I am going to show you a picture now, Ms. Lopez’’; ‘‘Mr. Rodriguez, look at me now’’; ‘‘Mr. Woo, please pay close attention.’’); make sure the client has established eye contact with you or with the stimulus before you present the stimulus Verbally reinforce the client for maintaining eye contact, looking at the treatment stimuli, concentrating on treatment tasks, performing accurately on tasks on hand Give corrective feedback; stop the client as soon as you find his or her attention wandering; reinstruct, reorient, draw attention, and continue with treatment trials Experiment with the loudness of your voice; some clients may need a louder and more intoned voice; others may react better to soft voice and speech Limit choices offered in treatment tasks (e.g., put only a few stimulus item in front of a patient with brain injury) Use manual guidance in the case of severely impaired clients to orient their face toward the stimuli; use touch to draw attention; guide the patient’s hand toward required manual tasks (e.g., pointing to a correct picture in a stimulus array) Give necessary intertribal interval time; do not rush stimulus presentations; but do not wait too long between stimulus presentations as this would give room for competing responses Judge the patient’s physical endurance; hold brief sessions if the patient fatigues easily; take short breaks during treatment; hold sessions at times when the patient is well rested 116
Attention Disorders A ● Shape attending behaviors; increase the duration of re-

quired attention gradually (e.g., initially set a realistic goal of attending to a task for only a few seconds and gradually increase the duration); reinforce for all on-task behaviors Teach the client to make appropriate requests that help him or her concentrate (e.g., requesting others to turn down the music, close a door or a window to reduce outside noise, speak louder or softer) Teach the client to organize his or her belongings into categories and keep them separately (e.g., writing and reading items in one place, such personal care items as toothbrush and razor in a different place) Use high probability behaviors to reinforce attending behaviors (e.g., good attending behavior in an earlier portion of treatment may mean that the patient can have a rest or watch TV) Teach the patient to assess and verify his or her work to promote self-correction (e.g., ask the client how she or he did in concentrating on a task on hand; give feedback; encourage realistic self-evaluations) Measure duration of attending behaviors and the frequency of inattentive behaviors to document changes and improvements; give this informational feedback to the patient (e.g., ‘‘Yesterday you could concentrate only for 2 minutes; today you concentrated for 3 minutes.’’) Teach the patient to cue himself or herself (e.g., by repeating instructions and reading a list of steps to be taken in completing a task before beginning the task) Teach family members to prompt and reinforce attending behaviors; to draw attention; to repeat instructions; and so forth

Audience Generalization.
Production of unreinforced responses in the presence of persons not involved in training; a strategy necessary in almost all cases to achieve generalized production of clinically established behaviors. ● Invite persons not involved in training to treatment sessions conducted in later stages of therapy ● Evoke behavior (e.g., fluency, correct production of speech sounds, naming, appropriate vocal qualities) ● Reinforce target behavior ● Have the visitor engage the client in conversational speech ● Have the visitor reinforce the target communication skills ● Take the client to nonclinical situations and evoke and reinforce target communication skills in the presence of other persons
Auditory Discrimination Training.
Treatment designed to teach clients to distinguish between correct and incorrect articulation of speech produced by the clinician and other persons; used on the assumption that misarticulations are due to a failure to hear differences between different speech sounds and that auditory discrimination training is a precursor to speech sound production training; assumption questioned by some clinicians who cite experimental evidence showing that production training will induce discrimination as well; same as Perceptual Training, a part of several traditional articulation treatment programs; a clinically practical strategy is to train production first and then probe for discrimination and train discrimination only if sound discrimination problems persist and negatively affect communication; it is likely that in most cases, production training will be sufficient to generate auditory discrimination as well. ● Describe the target sound, how it is made, and how it sounds 118
Augmentative Communication A ● Produce words and phrases that contain the target sound
as well as nontarget sounds
● Ask the client to respond in some way to the production
●
●
● ●
of the target sound (by raising the right hand or by pointing to the drawing of a smiling face) Produce a word with the correct sound and a word with a sound the client substitutes for a correct sound (e.g., radio and wadio) Ask the client to respond to the correct production (/r/ in radio) in one manner (pointing to the drawing of a smiling face) and to the incorrect production (/w/ in wadio) in a different manner (pointing to the drawing of a frowning face) Produce many words and phrases that are loaded with the target sounds to provide intense auditory stimulation Move on to production training, as there is little or no evidence that auditory discrimination training will result in correct production of speech sounds
Augmentative and Alternative Communication. Augmentative communication includes methods of communication that enhance and expand extremely limited oral means of communication by nonvocal means; alternative communication includes methods that replace oral communication by teaching substitute modes of communication; augmentative alternative methods may be integrated in rehabilitation; some augmentative communication may involve speech generated mechanically; includes various means of communication, some of which are more technologically oriented than others; usually used for persons who have limited oral communication skills because of severe clinical conditions including aphasia, autism, cerebral palsy, and other neurological disorders, deafness, dementia, dysarthria, glossectomy, intubation, laryngectomy, mental retardation, tracheostomy, and traumatic head injury; for procedures, see Augmentative Communication, Gestural (Unaided); Augmentative Communication, Gestural-Assisted (Aided); Augmentative Communication, Neuro-Assisted (Aided). 119
Augmentative Communication, Aided A Basic Principles of Selecting an Augmentative Communication Mode or System ● Assess the client’s speech as well as nonspeech com-
munication potential
● Consider the client’s strengths and limitations
• cognitive level • sensory disabilities • motor status • language comprehension ● Select a mode or system that gives the maximum advantage to the client ● Consider cost ● Consider the client’s acceptance of the mode or system ● Consider the communicative demands the client faces ● Consider the amount of training required ● Consider how the client and the family will use the mode or system Augmentative Communication, Aided. Methods of communication that enhance or expand (and rarely substitute) vocal communication by such external aids as an alphabet letter board or a computer.
Augmentative Communication, Gestural (Unaided). Methods of communication that use patterned muscle movements (gestures) to enhance oral communication but do not use instruments or external aids; gestures play a crucial role in conveying the speaker’s message; appropriate for all persons with severely impaired oral, expressive communication. ● Teach gestures for Yes and No to all speakers with extremely limited expressive oral communication because of severely impaired motor performance but relatively intact receptive language • teach the client to gesture Yes or No in response to a series of common questions with a carrier phrase ‘‘Do ?’’ you want • shape a clear gesture that all communication partners can understand 120
Augmentative Communication (Unaided) A

• model the gesture if necessary • reinforce consistently discriminated responding (client always gives the gesture that is meant) • consider the following gestures: head movements (side to side for No and up and down for Yes); eye movements (looking up for Yes and down for No; blinking once for Yes and twice for No; blinking the right eye for Yes and the left eye for No); hand movements (thumbs up for Yes and thumbs down for No;) feet movements (right foot movement for Yes and the left foot movement for No) Teach a pattern of eye-blinks that convey certain basic messages; for instance, beyond the Yes and No teach the client to: • blink three times to say I am hungry • blink four times to say I am thirsty • blink five times to say I need to go to bathroom Teach pointing to objects needed • teach finger pointing • teach pointing by directing gaze Teach the Left-Hand Manual Alphabet • consider teaching the left-hand manual alphabet for clients whose right hand is paralyzed • consider teaching the Manual Shorthand, which combines gestures with letters from the left-hand manual alphabet (talking hand system) Teach Pantomime • teach the client to use pantomime along with speech • teach initially a few mimed concepts that help communicative basic needs • expand the mimed repertoire as the client becomes more competent in its use • fade mimes if and when the client regains or improves oral speech Teach American Indian Hand Talk (AMER-IND) • teach first the signs that express mands (basic needs, requests) 121
Aug Comm, Gestural-Assisted (Aided) A • teach the one-hand version for those with one paralyzed hand • teach signs that express concrete ideas first and those that express abstract ideas later ● Teach American Sign Language (ASL or AMESLAN) • select initially the signs that express Mands (basic needs, requests) • teach signs that express concrete ideas first and those that express abstract ideas later Beukelman, D. R., & Mirenda, P. (1998). Augmentative and alternative communication: Management of severe communication disorders in children and adults (2nd ed.). Baltimore, MD: Paul H. Brookes. Glennen, S. L., & DeCoste, D. (1997). Handbook of augmentative and alternative communication. San Diego: Singular Publishing Group. Silverman, F. H. (1995). Communication for the speechless (3rd ed.). Boston: Allyn and Bacon.
Augmentative Communication, Gestural-Assisted (Aided). Methods of communication in which gestures are used to (a) select or scan messages displayed on a nonmechanical device (e.g., a communication board) or (b) display messages on a mechanical device (e.g., a computer monitor); used with many persons with minimal expressive language; the initial use of gestural-assisted means may promote appropriate vocalization or word productions in many clients; the emergent vocal productions may be strengthened and expanded; includes a variety of nonmechanical and mechanical methods.
Use Pictures and Symbols to Teach Functional Communication ● Teach the client to communicate with photographs and
drawings that may be displayed on a communication board • teach the client with limited cognitive functions to communicate basic needs with regular or miniaturized objects (e.g., the client points to a fork to indicate he or she wants to eat) 122
Aug Comm, Gestural-Assisted (Aided) A • teach the client to express a particular message through a picture (e.g., teach the client to point to or look at a picture of a person sleeping to communicate that he or she is tired or sleepy) • teach the client to express bodily states (e.g., pain in a certain part) by pointing to or looking at specific body parts on a line drawing ● Teach the client to communicate with various symbols that may be displayed on a communication board; select among many symbol systems that are available on the market; for instance: • Picsyms, a set of graphic symbols that represent nouns, verbs, and prepositions • Pic Symbols (Pictogram Ideogram Communication), which are white drawings on a black background • Sig Symbols which are based on American Sign Language (ASL); use them especially in conjunction with ASL • Blissymbolics which are a set of semi-iconic and abstract symbols that can be taught to persons of any language; teach the client to combine symbols to form more complex messages • Premack-type Symbols, or the Carrier Symbols which are abstract plastic shapes; associate words and phrases with each shape; teach the client to arrange and rearrange the plastic shapes like printed words • traditional orthography (e.g., the English alphabet); teach the client to spell out the word (by pointing to or scanning) along with the alphabet, display digits 1 through 10 and a set of common phrases or sentences so that not every word has to be spelled out or scanned (Scanning in Augmentative Communication) ● Teach the client to communicate with Rebuses • use rebuses (pictures that represent objects or events along with words, grammatic morphemes, or both) 123
Aug Comm, Gestural-Assisted (Aided) A • teach the client to add grammatic morphemes to a picture or a word (e.g., adding s to the picture of a book to suggest books) • combine rebuses to form more complex utterances
Use Nonelectronic Communication Boards to Teach Functional Communication ● Teach the client to communicate with messages on a
nonelectronic communication board • design a board of paper, cardboard, fabric, wood, or cork; if practical, prepare a book of symbols and written messages; select a board that all conversational partners can see simultaneously; portable, if necessary; attractive to look at; big enough to contain critical elements of the system; not overwhelmingly big or complex • write symbols (alphabets, orthographic messages, pictures, various kinds of symbols) on separate cards that can be mounted on the board • teach the client who cannot point (because of extremely limited motoric performance) to scan the message: you offer selections and the client indicates Yes to the right selection (e.g., You point to the word ‘‘food,’’ or a symbol for it, or a picture of a food item; the client indicates Yes or No) • teach the client to encode a message by pointing to a number printed on a separate, smaller, portable selection chart; have the messages on a larger communication board numbered: let the client point to a number on the selection chart; decode the number into the message on the board (e.g., if the client points to #5, it may mean ‘‘I am hungry’’ as per the communication board) • teach the client to directly select the message: teach the client to select the actual message on the board, instead of a number which stands for a message; teach clients to select by means of pointing and other 124
Aug Comm, Gestural-Assisted (Aided) A hand gestures, finger movements, eye gestures, gaze, headpointers, or headsticks. ● Teach the client to communicate by drawing symbols or pictures • teach the client to draw simple line drawings to communicate • let the client use paper, magic slate, or any other convenient surface ● Teach the client to communicate by writing (Traditional Orthography) • teach conventional writing to nonverbal children who can master it • teach them initially to write simple, functional messages • teach them to write more complex messages
Use Electronic Communication Systems to Teach Functional Communication ● Select an appropriate system for the client; consider the
cost, ease of use, and efficiency of the system
● Select an appropriate and practical switching mecha-
nism that the client can use with little effort and learn to generate signals for the electronic device (such as those that are specially constructed or a modified or regular microcomputer); consider push switches, push plates (plate-like structures that when touched will generate a signal), large and specially designed keyboards, joy sticks, squeeze bulbs, and several other available types of selection devices ● Select an appropriate display system to show messages when the client activates the switching mechanism; these may be computer screens, liquid-crystal displays (found on calculators), printed outputs (as with a computer printer), and many other kinds of special displays ● Select an appropriate control electronic unit (a dedicated augmentative communication unit or a computer) ● Teach the client to use the device; start with simpler messages; give plenty of practice in using the switching 125
Aug Comm, High Technology A mechanism; increase the complexity of messages in gradual steps; train the communicative partners in the environment Beukelman, D. R., & Mirenda, P. (1998). Augmentative and alternative communication: Management of severe communication disorders in children and adults (2nd ed.). Baltimore, MD: Paul H. Brookes. Silverman, F. H. (1995). Communication for the speechless (3rd ed.). Boston: Allyn and Bacon.
Augmentative Communication, High Technology. Methods of communication that enhance or expand (and rarely substitute for) vocal communication by external means that use sophisticated electronic technology, including computers; generate speech or printed messages; usually software run; more versatile than low-technology augmentative communication.
Augmentative Communication, Low Technology. Methods of communication that enhance or expand (and rarely substitute) vocal communication by external means that use no or limited electronic technology; there is no message storage, printed output, or speech output; a communication board with letters and words on it is an example.
Augmentative Communication, Neuro-Assisted (Aided). Methods of communication that use such bioelectrical signals as muscle action potentials to activate and display messages on a computer monitor; technically, a variety of switching devices; used for persons who are so profoundly impaired motorically that they cannot use a manual switching device; the communicator needs to have electrodes attached to the skin surface to pick-up and transmit muscle action potential signals to the device; this technology is not well developed. ● Train the client to use muscle action potentials to generate signals to an electronic communication device
126
Augmentative Communication, Unaided A • teach the client to vary muscle action potentials through biofeedback training • use a myoswitch that picks up muscle action potential from contracting muscles and transmits the impulse to an electronic device • use any of the several electronic devices available that have been modified for this purpose Beukelman, D. R., & Mirenda, P. (1992). Augmentative and alternative communication: Management of severe communication disorders in children and adults. Baltimore, MD: Paul H. Brookes. Silverman, F. H. (1995). Communication for the speechless (3rd ed.). Boston: Allyn and Bacon.
Augmentative Communication, Unaided. Methods of communication that enhance or expand (and rarely substitute for) vocal communication without external or mechanical aids; includes a more formal, systematic, intensive, or extensive use of gestures, signs, and facial expressions to supplement oral (speech) communication. Aural Rehabilitation. An educational and clinical program implemented, for the most part, by audiologists; includes the assessment of hearing impairment in adults and children; counseling; selection and fitting of hearing aids and auditory training; use of group amplification systems in educational and communication training sessions; often implemented by a team of specialists including audiologist, otologist, special education specialists, psychologists, and speech-language pathologists; for speech-language pathologists’ treatment of communication disorders in persons with hearing problems, see Hearing Impairment; also see Hard of Hearing; and Hearing Loss; note that in an aural rehabilitation program, the following are an audiologist’s responsibilities: ● Counseling clients with hearing impairment • giving information to persons with hearing impairment on available services

Autism: Communication A frequency and duration of breaks; begin to control what the child does during breaks ● Sit in front of the child, with the child’s legs between yours; gradually, move the chairs closer to the table and begin working off the table top ● Select appropriate and strong reinforcers because motivating children with autism is extremely important; much of the success may depend on whether you have a functional reinforcer for the child; use tokens and have a variety of back-up reinforcers available; select activities the child chooses on his or her own; make access to those activities the back-up reinforcer for tokens
Teaching Language and Communication to Autistic Children ● Use objects, not pictures, as stimuli to promote gener-
alized production of target skills in natural settings
● Teach in a variety of linguistic contexts (e.g., teach
● ●
●
●
●
grammatic morphemes in several phrases and sentences with varied linguistic contexts) Teach in a variety of environments (e.g., extend treatment to home, school, and other settings) Reduce Echolalia (find out if echolalia is functional; some evidence suggests that teaching autistic children to make requests may reduce echolalia) Give direct, intensive training (repeat trials and provide frequent training; target useful skills and teach them directly) Reinforce any attempt at appropriate communication (e.g., words, phrases, gestures, functional echolalia); gradually shift the reinforcement contingency to more precise, socially appropriate, complex, verbal responses Reduce autistic leading (tendency to grasp an adult’s hand and leading to a desired object) by teaching them to point to things desired

Automatic Reinforcers.
Sensory consequences of responses that reinforce those responses (e.g., the sensation a child with autism derives from banging his or her head). Autosomal Dominant. Any chromosome apart from the sex chromosome is autosomal; not sex-linked; dominant indicates that the defective gene dominates its normal partner in its phenotypic expression. Aversive Stimuli. Events that people work hard to avoid or move away from; reduction in aversive stimulation is the essence of negative reinforcement; a behavior that reduces negative experiences tends to increase in frequency; in treatment, positive reinforcement is preferable to negative reinforcement. Avoidance. A behavior that prevents the occurrence of an aversive event and hence is reinforced; negatively reinforced behavior; in treatment, target is to reduce avoidance if judged undesirable; a typical target in persons who stutter; typically, the client is made to face previously avoided situations with appropriate clinical support; for instance, in reducing avoidance of certain speaking situations by persons who stutter: ● Build a hierarchy of most to least frequently avoided speaking situations or tasks ● As the client becomes more fluent during treatment, introduce the client to least frequently avoided situations first and move up the hierarchy ● Offer training in situations the clients avoids; for instance: • take the client to a restaurant and have him or her order food (an avoided responses); monitor fluency and provide subtle reinforcement and corrective feedback 134
Avoidance A • have the client make phone calls as you monitor fluency (e.g., prompt the person to slow down) • arrange group situations in which the client will speak or make brief presentations • introduce strangers to the treatment setting and let the client practice fluency skills in front of them ● Generally, reinforce the client for facing previously avoided situations and tasks
135
137
Backup Reinforcers B
Backup Reinforcers.
Events, objects, and opportunities for selected behaviors that become available to clients who exchange their earned tokens in treatment sessions. ● Have a collection of backup reinforcers ● Give tokens to reinforce target responses ● Exchange tokens for selected events, objects, or opportunities for certain behaviors
Basal Ganglia. Structures located deep within the brain and just above midbrain that are important for movement control; part of the extrapyramidal system; include the caudate nucleus, the putamen nucleus, and globus pallidus.
Baselines. Recorded rates of responses in the absence of planned intervention; also known as the operant level of a response; reliability or stability of repeated measures is a required characteristic; help establish the clinician accountability; in treatment research, help rule out extraneous variables; a necessary measure before starting treatment in all cases; should be established in Baselines, Conversational Speech and Discrete Trials, Evoked and Discrete Trials, Modeled formats.
Baselines, Conversational Speech. Measures of target behaviors produced in conversational speech in the absence of treatment; an important pretreatment measure. ● Record a conversational speech sample in as naturalistic a manner as possible • with children, have toys, pictures, books, and other materials to evoke speech; engage the child in conversational speech with the help of the materials; if necessary, focus on the target features to be measured (e.g., drawing the child’s attention to actions you perform to evoke the ing) • with adults, conduct conversation on their favorite topics • in most cases, the client interview might also be used to measure the production of target behaviors 138
Baseline, Discrete Trials ● measure the correct and incorrect productions of the tar-
get behaviors in the sample
● calculate the percent correct baseline response rate
Baseline, Discrete Trials. Baselines of target behaviors established in discrete trials in which a client’s multiple attempts to produce a target response are counted separately; trials are separated in time; should be established in both the evoked trials and modeled trials format. ● Select target behaviors (phoneme productions, grammatic morphemes, sentence structures, pragmatic skills, fluent productions, naming skills, etc.) ● Specify target behaviors in measurable terms; for instance • production of /s/ in word initial positions • production of present progressive ing • naming pictures • reduced rate of speech • elimination of hard glottal attacks ● Prepare stimulus items to evoke target responses; in the case of speech and language targets, prepare 20 stimulus items for each target response; for instance • twenty pictures that help evoke 20 words with /s/ in the initial position • twenty sentences with the present progressive feature in them (e.g., The boy is walking.) ● Prepare questions to be asked to evoke the response, and the exact way of modeling the response ● Prepare recording sheet ● Select type: Baseline Evoked Trials or Baseline Modeled Trials ● Analyze data to calculate percentage of correct responses (e.g., 50% correct production of the /s/ in word initial positions; 75% correct production of ing in sentences) ● Repeat measures; compare the discrete trial and conversational speech measures ● When measures are stable, begin treatment 139
B
Baseline Evoked Trials B
Baseline Evoked Trials. Discrete baseline trials that are temporally separated; each attempt to produce a target behavior is discretely measured; no modeling of the target response; no consequences for the correct or incorrect responses. ● Place stimulus item in front of client (e.g., a picture of a ball) or demonstrate an action (e.g., moving a toy car) ● Ask the relevant predetermined question (e.g., ‘‘What is this?’’ ‘‘What am I doing?’’ or ‘‘What is happening?’’) ● Wait a few seconds for the client to respond ● Record the client’s response on the recording sheet ● Remove the stimulus item (move it toward you, away from the client) ● Wait 2–3 seconds to signify the end of a trial ● Begin the next trial with a different item
Baseline Modeled Trials. A discrete baseline trial in which the clinician models the correct response for the client to imitate; no consequences for the correct or incorrect responses. ● Place a stimulus item in front of the client or demonstrate an action ● Ask the predetermined question (e.g., ‘‘What is this?’’) Immediately model the correct response (e.g., ‘‘Johnny, say ball.’’) ● Wait a few seconds for the client to respond ● Record the client’s response on the recording sheet ● Remove the stimulus item (move it toward you, away from the client) ● Wait 2–3 seconds to signify the end of a trial ● Begin the next trial with a different stimulus item
Behavioral Contingency. In behavioral analysis and treatment, a dependent relationship between Antecedents, responses, and Consequences; in behavioral treatment, clinician manages this contingency by: ● Providing antecedents (stimuli, modeling, instruction, demonstration, etc.) 140
Behavioral Momentum ● Requiring a specified response ● Providing immediate consequences in the form of positive
reinforcers or corrective feedback
Behavioral Momentum.
A behavioral treatment procedure in which the clinician rapidly and repeatedly evokes a high-probability response and then immediately commands a low-probability response; often used to reduce noncompliance; in increasing the frequency of a low-probability response: ● Find a response the client readily performs (e.g., hand clapping) ● Model and have the child imitate that high-probability response repeatedly and in rapid succession ● Immediately, ask the child to open his or her mouth (an example of a low-probability response) ● Reinforce the occurrence of the low-probability response
Biofeedback.
A method used to reduce incorrect responses or shape and increase desirable responses in treatment; includes mechanical feedback given to the client on vocal pitch and intensity, respiration, galvanic skin response, and muscle action potential level.
Bite Block. A small block of acrylic or putty custom-made for a client who holds it between the lateral upper and lower teeth; observed to improve speech intelligibility in clients who have abnormal jaw movements; recommended for some clients with dysarthria.
Blissymbolics. A set of symbols used to communicate nonorally; meant to be an international language; more widely applied and researched than other symbol systems in teaching communication to severely handicapped clients; symbols may be combined to form complex expressions; developed by C. Bliss; see Augmentative Communication, Gestural-Assisted (Aided).
Bolus. A mass of chewed or otherwise prepared food moved as a unit in the act of swallowing. 141
B
Booster Treatment B
Booster Treatment. Treatment given any time after the client was dismissed from the original treatment; part of response maintenance strategy. ● Conduct periodic follow-ups ● If the follow-up measures show decline in response rate, give booster treatment ● Use the original or newer, more effective procedures
Botulinum Toxin Injection. A medical treatment procedure for neurogenic or idiopathic adductor spasmodic dysphonia and adductor spasmodic dysphonia that does not respond to behavioral treatment; botulinum toxin is injected into the thyroarytenoid muscle unilaterally or bilaterally; effects last about 3 months.
Bradykinesia. Slowness of movements; difficulty in stopping movement once initiated; freezing of movement.
Breathiness. A voice quality that results when there is excessive air leakage during phonation because of inadequate approximation of the vocal folds; caused by various factors; treatment varies by cause.
142
143
Carrier Symbols Carrier Symbols. A set of plastic symbols (adapted from
C
the Premack symbols) used in teaching nonverbal communication; used as a part of the Non-SLIP (Non-Speech Language Initiation Program); once learned, the program helps initiate oral speech training; developed and researched by J. Carrier.
Carry-over. Generalized production of any behavior taught in a special setting in natural and untreated settings and in relation to novel stimuli; an important goal of clinical intervention; the same as Generalization.
Cathode-ray Display (CRT). A video display system used in many desktop computers; more easily read under varied lighting conditions than the Liquid Crystal Display; used in some devices of Augmentative and Alternative Communication (ACC).
Cerebral Palsy.
A congenital, nonprogressive neurological disorder that affects motor control; caused by injury to the cerebral levels during the prenatal or perinatal period; symptoms tend to improve with growth; causes speech disorders, mostly dysarthria; symptoms related to speech include respiratory control problems, laryngeal dysfunction resulting in voice problems, possible velopharyngeal inadequacy, potential language disorders, and significant articulation problems (dysarthria); may involve cognitive functions; may be associated with feeding problems.
Classification of Cerebral Palsy
● Ataxic Cerebral Palsy: Ataxia, disturbed balance and move-
ment, is the main characteristic; injury to the cerebellum.
● Athetoid Cerebral Palsy: Athetosis, characterized by slow,
involuntary, writhing movements, is the distinguishing feature; injury to the extrapyramidal motor pathways, especially to the basal ganglia. ● Spastic Cerebral Palsy: Increased tone or rigidity of muscles is the distinguishing feature; the most common type; in144
Cerebral Palsy jury to the pyramidal motor pathways and the higher cortical centers of motor control.
Treatment of Cerebral Palsy General Principles ● Work closely with the team of specialists serving children with cerebral palsy ● Counsel parents about the effects of cerebral palsy on communication and their role in stimulating language at home ● Work closely with parents throughout the treatment duration ● Make a thorough assessment of communication problems and design treatment to suit the child’s problems, needs, and strengths ● Consider educational demands made or to be made on the child in planning treatment; work closely with educators ● Borrow techniques from other communicative disorders in children (e.g., language disorders, articulation and phonological disorders, dysarthria, voice disorders) as cerebral palsy is not the name of a unique speech disorder; modify the standard techniques to suit the individual child and his or her specific symptom complex Treatment Procedures ● Treatment of language disorders • train parents to stimulate language at home; see Parent Training and Language Stimulation by Parents • assess the child’s language development periodically to determine the need for formal clinical treatment • implement formal language treatment if necessary • use the treatment procedures described under Language Disorders in Children and modify the procedures to suit the individual child with cerebral palsy ● Treatment of voice disorders • diagnose the specific voice disorder; when appropriate, use one or more treatment techniques described 145

Chaining
C
under Voice Disorders techniques with suitable modifications; be aware that voice disorders may be due to respiratory problems associated with cerebral palsy • treat associated respiratory problems; prescribe exercises to improve breath support for speech; use techniques described under Dysarthria, Treatment • treat velopharyngeal incompetence only if there is enough tissue mass, and behavioral training thus is likely to be effective; see Treatment of Voice Disorders and Treatment of Disorders of Resonance ● Treatment of articulation and phonological disorders • assess the child’s specific sound errors and error patterns • assess the compensatory articulatory postures the child uses • modify or eliminate inappropriate and ineffective compensatory postures • teach the specific phonemes or classes of phonemes based on distinctive features or phonological patterns • use the treatment techniques described under Articulation and Phonological Disorders with appropriate modifications
Chaining. A behavioral technique of linking elements of a complex skill; similar to shaping; useful in teaching a variety of nonverbal and verbal skills, although most frequently employed in teaching self-help skills; includes forward chaining and backward chaining. ● Initially, make a task analysis and identify the steps involved in achieving a complex task (e.g., in teaching a child to tie his or her shoe lace, identify such different individual tasks as: 1. inserting the foot in to a shoe, 2. pulling the lace ends together, 3. making a bow, and 4. making the final knot) ● Use backward chaining to teach the skills in the reverse order and then practice the skill in an integrated manner: 146
Changing Criterion • prompt and manually guide the child through skill 3; stop direct assistance and prompt the child to take the final step of making a knot (skill 4) • starting all over, prompt and manually guide the child through skill 2; prompt the child to perform skill 3, making a bow out of the two lace ends • starting over, prompt and manually guide the child to perform skill 1; stop and prompt the child to perform skill 2 • starting over, prompt the child to perform all four skills, ending in a knotted shoe lace ● Use forward chaining to teach skills in their sequence of first skill component to the last skill and practice the total skills in an integrated manner • use essentially the same procedure as in backward chaining except begin with skill 1 and move through the sequence
Changing Criterion, Research Design.
A singlesubject research design to evaluate treatment effects; effectiveness of a treatment is demonstrated by effecting changes in target behaviors that approximate a changing criterion of performance; in successive stages of treatment, the behavior is held to a lower or higher criterion.
Changing Criterion, Treatment Procedure. A method of shaping desirable behaviors by using performance criteria that change every time the client meets a certain criterion; the criterion may change in either direction (lower or higher) depending on the target behavior; in reducing the speech rate of clients with certain communicative disorders, the criteria are progressively lower; in shaping longer utterances, the criteria are progressively higher.
Chant-Talk.
A voice therapy technique characterized by speech that resembles chanting; consists of soft glottal attacks; raised pitch, prolonged syllables, even stress, and smooth 147

blending of words; considered appropriate for hyperfunctional voice problems; helps reduce excessive muscular effort and tension associated with voice production; for procedures, see Specific Normal Voice Facilitating Techniques under Voice Disorders.
Chewing Method. A voice therapy technique used to reduce vocal hyperfunction; helps reduce excessive tension and muscular effort associated with voice production; for procedures, see Specific Normal Voice Facilitating Techniques under Voice Disorders.
Child-Centered Approach. A child language intervention approach that assigns a more active role to the child; play-oriented and indirect treatment method; clinician takes the child’s lead in targeting language structures for intervention; see Language Disorders in Children; Treatment of Language Disorders: Specific Techniques or Programs.
Childhood Aphasia (Congenital Aphasia). A controversial and somewhat dated term used to describe certain children’s language disorders that could not be explained on the basis of other known variables including neurological problems, hearing impairment, mental retardation, environmental deficit, and so forth; a diagnosis made on negative evidence; questioned or rejected by many clinicians.
Choreiform Movements. Jerky, irregular, involuntary, and rapid movements; caused by damage to the caudate and the putamen; major symptom of Huntington’s Disease.
Circumlocutions. Talking around a theme or failing to use specific terms.
Cleft. An opening in a structure that is normally closed. Cleft Lip. Opening in the upper lip; may be on one (unilateral) or both (bilateral) sides of the lip; due to failure in embryonic growth processes.
148
Cleft Palate: Surgical Management Cleft Palate. Opening in the palate, the structure that separates the oral and nasal cavities; varies in extent and severity and may extend from the upper lip to the soft palate; due to failures in embryonic growth processes.
Surgical Management of the Clefts

clefts; usually done when the baby is about 3 months old or weighs about 10 pounds. Palatal Surgery. Surgical procedures performed to close the cleft or clefts of the palate; done when the baby is between 9 and 24 months, many between 9 and 12 months; the earlier the closure of the cleft, the better the speech development. V-Y Retroposition. A surgical method to repair the cleft of the palate; also known as Veau-Wardill-Kilner procedure; clefts are closed by raising from the bone single-based flaps of palatal mucoperiosteum on either side of the cleft and closing the cleft with the flaps as they are pushed back to lengthen the palate; improves chances of better speech production. von Langenbeck Method. A surgical method to repair the cleft of the palate by raising two bipedicled (attached on both ends) flaps of mucoperiosteum, bringing them together, and attaching them; leaves denuded bone on either side; does not lengthen the palate. Delayed Hard Palate Closure. A surgical sequence to close the cleft in which the soft palatal cleft is closed first and the hard palatal cleft is closed later. Primary Surgery for the Clefts. The initial surgery in which the clefts are closed. Pharyngeal Flap. A secondary palatal surgical procedure designed to improve the velopharyngeal functioning for speech; a muscular flap is cut from the posterior pharyngeal wall, raised, and attached to the velum; the flap is open on either side to allow for nasal breathing, nasal drainage,

and production of nasal speech sounds; helps close the velopharyngeal port and thus reduce hypernasality. ● Pharyngoplasty. A surgical procedure designed to improve velopharyngeal incompetence; such substances as Teflon, silicone, dacron wool/silicone gel bag, and cartilage may be implanted or injected into the posterior pharyngeal wall to make it bulge and thus help close the velopharyngeal port. ● Secondary Surgeries for Clefts. Surgical procedures done after the primary surgery to improve functioning and appearance. Bzoch, K. R. (1997). Communication disorders related to cleft lip and palate (4th ed.). Austin, TX: Pro-Ed.

Cleft Lip and Palate: Treatment for Articulation and Phonological Disorders General Principles ● A thorough assessment of articulation skills and velopharyngeal function is necessary before starting treatment ● Treatment is effective if the child has at least a marginal velopharyngeal competence ● Children with significant velopharyngeal incompetence need surgery, prosthetic assistance, or both ● Treatment should be offered as early as possible ● Treatment should emphasize production and not auditory discrimination ● Trial therapy may be needed to determine prognosis ● Behavioral principles and procedures are effective in teaching correct articulation ● Phonological approach may be appropriate in certain children with repaired cleft 150
Cleft Palate: Articulation Disorders ● Many techniques used to treat Articulation and Pho-
nological Disorders in children without clefts are appropriate in teaching sound production to children with repaired clefts Treatment Procedures: Articulation and Phonological Disorders Use the procedures of treating Articulation and Phonological Disorders; consider the following suggestions, some of which are unique to children with repaired clefts. ● Educate parents about the speech mechanism ● Withhold reinforcement for undesirable compensatory behaviors, the need for which has been eliminated by medical treatment ● Teach the more visible sounds before the less visible except for the linguadentals ● Teach stops and fricatives before other class of sounds ● Avoid or postpone training on /k/ and /g/ if the velopharyngeal functioning is inadequate ● Teach fricatives, affricates, or both if they are stimulable or after stops are mastered ● Teach linguapalatal sounds, lingua-alveolars, and linguadentals in that order ● Progress from syllables to words, phrases, and sentences ● Give auditory and visual cues; model frequently ● Provide systematic practice and reinforce correct productions ● Introduce compensatory articulatory positioning where appropriate ● Teach the client to direct the breath stream orally; let the child feel the airstream on hand or see the movement of a piece of tissue ● Teach the child to avoid posterior articulatory placements 151

● Give tactile cues and instruction to improve tongue
positioning
● Work on generalization and maintenance; train par-
ents to reinforce correct articulation at home Bzoch, K. R. (1997). Communication disorders related to cleft lip and palate (4th ed.). Austin, TX: Pro-Ed. McWilliams, B. J., Morris, H.

Cleft Lip and Palate: Treatment of Language Disorders General Principles ● Language stimulation by parents may be all that is needed in some cases ● Formal language treatment may be necessary in some cases ● Need to work with the parents from early infancy to establish a long-term rapport ● Counseling parents about language development is essential ● The basic language treatment procedures are not much different from those used with Language Disorders in Children without clefts Treatment Procedures: Language Disorders Use the procedures of treating Language Disorders in Children without clefts; consider the following suggestions, some of which are unique to children with clefts. ● Teach patients to stimulate language at home ● Ask parents to encourage free verbal expression in their child 152
Cleft Palate: Phonatory Disorders ● Ask parents to integrate stimulation for articulation
and language
● Integrate information about all aspects of rehabili-
tation in your discussion with the parents
● Ask parents to socially reinforce the child’s sponta-
neous verbal productions
● Teach parents to reduce negative feedback, and
● ● ● ●
make more positive statements about the child’s communicative attempts Meet with parents regularly to review progress and modify their home language stimulation program Periodically assess the child’s language skills Start formal language treatment when one of the periodic assessments warrant it Consider the imminent educational demands and plan language intervention to help meet them
Cleft Lip and Palate: Treatment of Phonatory Disorders General Principles ● Phonatory problems may be due to compensatory behaviors or may be independent of velopharyngeal insufficiency ● Use techniques described under Voice Disorders if the problems are independent of velopharyngeal insufficiency (and due to vocal abuse) ● Consider phonatory treatment as diagnostic; discontinue if there is no improvement in phonatory problems or other speech symptoms worsen ● Do not try to eliminate nasal escape and hypernasality ● Do not offer phonatory treatment for children with a clear diagnosis of velopharyngeal incompetence ● Follow treated children because some improve, some deteriorate, and some stay the same Treatment Procedures for Hyperfunctional Voice ● Describe how voice is produced to the child and the parents 153
C
Cleft Palate: Resonance Disorders ● Reduce Vocally Abusive Behaviors in the child and in
C
other members of the family
● Counsel the family about good vocal behaviors (e.g.,
talking less in noisy environments, practicing soft speech, good conversational turn taking, clapping instead of shouting or yelling) ● Use auditory discrimination training by helping the child to discriminate his or her voice from that of other children without vocal nodules or other vocal pathology ● Use such biofeedback instruments as the Visi-Pitch in training ● Train healthy voice production by teaching the child to • reduce vocal loudness • eliminate hard glottal attacks • initiate words that start with vowels • use easy, gentle onset of phonation • self-monitor voice McWilliams, B. J., Morris, H. L., & Shelton, R. L. (1990). Cleft palate speech (2nd. ed.). Philadelphia: B. C. Decker.
Cleft Lip and Palate: Treatment for Resonance Disorders General Principles ● Do not treat Hypernasality if it is a result of velopharyngeal incompetence ● Treat hypernasality only if the child is capable of achieving velopharyngeal closure ● See if surgery reduces or eliminates hypernasality; improvement may continue for up to a year following surgery Treatment Procedures: Resonance Disorders ● Use techniques described under Voice Disorders to reduce hypernasality including increased loudness, discrimination training to distinguish oral and nasal resonance, lowered pitch, encouraging increased oral opening ● Use respiratory training to improve loudness ● Attempt articulation with the nares occluded 154
Client-Specific Strategy ● Decrease intra-oral breath pressure on stop consonants
and fricatives, while simultaneously using loose articulatory contacts ● Use such biofeedback instruments as Tonar II to reduce hypernasality ● Use the whistle-blowing technique of R. J. Shprintzen and his associates to promote velopharyngeal closure during speech • teach whistling and blowing at the same time • reinforce when nasal airflow is absent • continue until there is no nasal escape during whistling or blowing • eliminate whistling or blowing, and introduce phonation • continue until no nasal escape is evident • introduce vowels /i/ or /u/ while blowing or whistling • continue until there is no longer nasal escape • eliminate blowing or whistling, and produce only the vowels • form monosyllables by using non-nasal consonants with vowels • move to words, sentences, and conversations • teach self-monitoring skills Boone, D.

clutter; may use Delayed Auditory Feedback (DAF) to induce rate reduction. ● Establish a baserate of speech rate measured either in syllables or words per minute ● Instruct the client in rate reduction and describe its desirable effects ● Reassure the client that a more acceptable rate is the final target of treatment ● Model a slow rate of speech for the client ● Model pausing at appropriate junctures ● Experiment with slower rates and increased frequency or duration of pauses that result in reduced or eliminated dysfluencies and improved intelligibility ● Model the effective rate selected for the client ● Ask the client to imitate the reduced rate ● Use delayed auditory feedback if instructions and modeling are not effective ● Start with words and phrases and move on to controlled and spontaneous sentences ● Add other targets (distinct articulation, increased stress, prolonged vowels) ● Fade excessively slow rate while maintaining distinct articulation and decreased dysfluencies ● Teach self-monitoring skills ● Follow up and arrange for booster treatment Collaborative Model. A service delivery model used in public schools; the speech-language pathologist works with the classroom teacher in identifying clinical activities that promote academic learning in a child with communication disorders; the clinician works in the classroom along with the teacher. Collagen Injection. A medical treatment procedure for clients with paralyzed vocal folds; injected into the middle third of the fold, collagen increases the bulk and the chances of adduction.
158
Communication Communication. Exchange of information through various verbal or nonverbal actions; more or less organized; target of treatment in clients with communicative disorders; its various forms include: ● Aided communication: Communication achieved through the assistance of such external devices as paper and pencil, communication boards, and computers. ● Alternative communication: Communication achieved by nonoral means; all modes others than the verbal. ● Augmentative communication: Oral or verbal communication that is in some way limited but enhanced or expanded by aided or unaided alternative communication means including speech synthesizers, communication boards, and paper and pencil. ● Manual communication: Communication achieved by signs, gestures, and symbols and without oral speech. ● Nonverbal communication: Communication achieved without oral speech; may be in the form of signs, gestures, facial expressions, and symbols. ● Simultaneous communication: Communication achieved through multiple means including oral speech, signs, symbols, and gestures. ● Total communication: Communication achieved through the simultaneous use of verbal expressions as well as a sign language (e.g., American Sign Language). ● Unaided communication: Communication achieved without the help of external means; normal oral communication that is accompanied by typical gestures and expressions. ● Verbal communication: Communication achieved through spoken words and language; may be accompanied by culturally appropriate normal gestures and facial expression Communication Boards. An augmentative/alternative communication system; boards on which letters, words, phrases, sentences, symbols, or pictures are pasted for the

client to point to, touch, or select in any manner possible to communicate.
Compensatory Strategies.
Means of achieving communication in unusual or atypical means; achieving communication in spite of organic, intellectual, or other kinds of deficiency that may be expected to affect communication; in articulation, methods of producing speech sounds in atypical means because of neuroanatomic deficiencies; in adult communication rehabilitation (such as in patients with dementia), communication through strategies that help adapt to deficiencies.
Completion. The same as Cloze Procedure and Partial Modeling.
Concurrent Stimulus-Response Generalization. Production of new and unreinforced responses in relation to new stimuli; the most complex form of generalized production.
Conditioned Generalized Reinforcers. Tokens, money, and other reinforcers that are effective in a wide range of conditions; Secondary Reinforcers that have a generalized effect; use them to: ● Promote generalized productions of target behaviors ● Enhance the effectiveness of the reinforces used in treatment
Conditioned Reinforcers. Events that reinforce behaviors because of past learning experiences (e.g., verbal praise or tokens); the same as Secondary Reinforcers; see Unconditioned Reinforcers.
Conditioned Response. A learned response reliably elicited or evoked by a conditioned stimulus; in clinical terms, a target response elicited or evoked and then reinforced; see Unconditioned Response. 160
Conditioned Stimulus Conditioned Stimulus. A stimulus that elicits or evokes a response only because of a learning history; stimuli clinicians use in treatment sessions; see Unconditioned Stimulus.
Conditioning and Learning. A behavioral method of selecting and strengthening behaviors in individuals; technique of teaching new behaviors; changing the probability of existing behaviors by arranging different consequences for behaviors: ● Avoidance conditioning: Learning or teaching behaviors that help avoid aversive conditions, stimuli, and persons; once learned, hard to extinguish; often found in persons who stutter; modifying such avoidance behaviors as not talking on the phone is a treatment target. ● Classical conditioning: Also known as Pavlovian conditioning, classical conditioning involves systematic pairing of two stimuli—one, an unconditioned stimulus(UCS) and the other a conditioned stimulus (CS) so that the CS begins to elicit the response typically given to the UCS. ● Operant conditioning: Creating, shaping, selecting, strengthening, or weakening behaviors of an individual by arranging different consequences for those behaviors; the most researched and effective techniques known to teach new skills, including communicative skills.
Conductive Hearing Loss. Inefficient conductance of sound to the middle or inner ear due to the abnormalities of the external auditory canal, the ear drum, or the ossicular chain of the middle ear.
Conduction Aphasia.
A type of fluent aphasia characterized by markedly impaired repetition skills; caused by lesions in the supramarginal gyrus, the superior temporal lobe, and regions between Broca’s and Wernicke’s areas. See Aphasia.
Confrontation Naming. Naming a stimulus when asked to do so; a correct response to such questions as ‘‘What is 161
C
Congenital Disorder
C
this?’’; typically impaired in patients with aphasia and hence a treatment target for clients with Aphasia.
Congenital Disorder.
Any clinical condition a person is born with; a condition noticed at the time of or soon after birth; may or may not be inherited.
Congenital Aphasia.
Aphasia noticed early in childhood; a disorder that affects the acquisition of language as against aphasia in adults that disrupts acquired language. The same as Childhood Aphasia.
Congenital Palatopharyngeal Incompetence.
An inadequate velopharyngeal mechanism that cannot close the velopharyngeal port for the production of nonnasal speech sounds; not due to clefts; the person is presumably born with a deficient velopharyngeal mechanism; hard palate may be too short or the nasopharynx may be too deep; speech is hypernasal; depending on the degree of incompetence, resonance (voice) therapy may be ineffective without surgical or prosthetic help.
Consequences. Events that follow a response and thus increase or decrease the future probability of those responses; in treatment, clinician’s differential response to client’s correct, incorrect, and no response; technically known as reinforcers (both positive and negative) that typically increase behaviors and punishers (corrective feedback) that decrease them.
Constituent Definitions. Dictionary definitions of terms with no reference to how what is defined is measured (e.g., The goal of treatment is to reduce stuttering.) contrasted with Operational Definitions (e.g., The goal of treatment is to reduce specified dysfluencies to below 3% of the words spoken.).
Consultant Model.
A service delivery model; the speechlanguage pathologist selects the training targets and procedures; trains teachers, parents, siblings, aides, and others 162
Contact Ulcers (Contact Granuloma) who actually provide the service; the clinician evaluates the results and modifies the procedures.
Contact Ulcers (Contact Granuloma). Benign lesions on the posterior third of the glottal margin; possibly due to trauma, reflux, or vocally abusive behaviors; voice symptoms include low pitch, effortful phonation, and vocal fatigue. ● Do not recommend complete vocal rest or surgical treatment ● Do not recommend forced whispering ● Ask the patient to talk less ● Reduce Vocally Abusive Behaviors ● Teach the client to speak with less effort and force ● Teach relaxed phonation and speaking ● Teach the client to speak more softly ● Eliminate glottal attacks
Contingency. An interdependent relation between events or factors; in behavioral analysis and treatment, a dependent relation between antecedents, responses, and the clinician’s feedback to the client; the most important element in behavioral treatment; includes Environmental Contingency and Genetic/Neurophysiological Contingency.
Contingent Consequences. Consequences that closely follow behaviors and thus change their frequency; in treatment, the feedback clinicians give their clients immediately after the clients produce correct or incorrect responses; consequences that depend on the nature of responses (correct or incorrect); reinforcers and punishers that depend on the responses.
Contingent Queries. Questions the clinician asks immediately following an unclear statement from the client in language therapy; lead to more specific or elaborate responses from the client. ● Ask a question immediately following an unclear response from the child (e.g., the child says ‘‘kick ball’’; you ask, 163
C
Continuous Airflow
C
‘‘Who is kicking the ball?’’); such contingent queries may lead to a more clear and perhaps elaborate response from the child.
Continuous Airflow. A stuttering treatment target; maintaining uninterrupted airflow throughout an utterance; for procedures see Stuttering, Treatment; Treatment of Stuttering: Specific Techniques or Programs.
Continuous Reinforcement. A schedule in which every occurrence of a response is reinforced; effective in establishing new skills; inefficient in maintaining already established skills; therefore: ● Use this schedule only in initial stage of treatment ● Gradually shift from continuous to Intermittent Reinforcement
Contrast Effect. Increase in the frequency of an undesirable response that has been kept under check by an aversive stimulus when the aversive stimulus is absent.
Contrastive Stress Drills. A treatment method used to promote both articulatory proficiency and natural prosody, especially the stress and rhythm aspects of spoken language; used in treating Apraxia of Speech (AOS) in Adults; different phrases and sentences are used to teach placing stress on different words; stressed words or terms may be used to promote articulatory proficiency or simply to vary prosodic features of speech.
In Teaching Articulatory Proficiency
● Construct phrases and sentences preferably with a single
target sound in them (e.g., ‘‘My name is Peter’’ for /p/; ‘‘Sam did it’’ for /s/) ● Ask a series of questions such that the client will respond with the target phrase placing extra stress on the target word (e.g., ‘‘Is your name Tom?’’; client will respond ‘‘No, my name is Peter’’; the client is likely to stress the word
164
Control Group Peter, especially the initial sound, and thus improve the articulatory precision of /p/; similarly, ask ‘‘Tom did it?’’; the client will respond ‘‘Sam did it.’’) ● Reinforce the client for articulatory proficiency
In Teaching Prosodic Features
● Create a series of phrases and sentences (e.g., ‘‘Tom does
not read mystery novels.’’)
● Ask questions that will force stress on different words in
target phrases and sentences (e.g., ‘‘Does Tom read romance novels?’’ may evoke ‘‘No, Tom reads mystery novels.’’ ‘‘Does Tom never read mystery novels?’’ may evoke ‘‘Tom reads them all the time.’’) ● Reinforce the client for varying stress on different words Control Group. The group that does not receive treatment and hence shows no change in the target disorder or disease; part of the Group Design Strategy that helps evaluate treatment effects and efficacy. ● Select subjects randomly (Random Selection) ● Assign subjects into control and experimental groups randomly ● Alternatively, match subjects in the experimental and control groups (see Matching) ● Assess the control group ● Withhold treatment to the control group while the experimental group receives treatment. ● Demonstrate that the control group did not change (improve) while the experimental group did Controlled Evidence. Data that show that a particular treatment, not some other factor, was responsible for the positive changes in a client’s behavior; evidence gathered through controlled experimentation with either group or single-subject design strategy; data that show that treatment is significantly better than no treatment; evidence that supports the use of a treatment technique; one of several Treatment Selection Criteria.
165
C
Controlled Sentences Controlled Sentences. Specific sentences that contain
C
target language features the clinician asks the child or an adult to produce; may be modeled; use of pictures and other clinical stimuli may be used to evoke them; less spontaneous.
Conversational Probes.
Methods to assess generalized production of clinically established behaviors in conversational speech and language. ● Take a naturalistic conversational speech sample ● Direct it minimally to adequately sample the production of speech or language behaviors under probe ● Count the number of opportunities for producing the skill under probe ● Calculate the percent correct production of probed behaviors ● Give additional training at the conversational level if the adopted probe criterion is not met (e.g., 90% accuracy) ● Dismiss the client only after the criterion is met
Conversational Turn Taking. A pragmatic language skill and treatment target; often deficient in a client with language disorders; involves appropriate exchange of speaker and listener roles during conversation; for procedures, see Language Disorders in Children; Treatment of Language Disorders: Specific Techniques or Programs.
Corrective Feedback.
Response-contingent feedback from the clinician that reduces the frequency of undesirable responses of clients; frequently used in treatment. ● Give corrective feedback as soon as you detect an incorrect response ● Give Verbal Corrective Feedback (‘‘No.’’ or ‘‘That is not correct.’’) for all incorrect responses ● Give Nonverbal Corrective Feedback when appropriate (gestures that show disapproval of a response) ● Give Mechanical Corrective Feedback or Biofeedback whenever possible 166
Craniocerebral Trauma ● Measure the frequency of incorrect responses to see if the
feedback is effective
● Replace ineffective forms of corrective feedback with
other, potentially more effective forms
● Minimize the use of corrective feedback by giving more
positive feedback for correct responses and by Shaping complex skills
Craniocerebral Trauma. The same as Traumatic Brain Injury.
Criteria for Making Clinical Decisions. Rules to make various clinical judgments; includes such treatmentrelated rules as when to model, when to stop modeling, and when a behavior is considered trained. ● Model most target behaviors for most clients, especially in the initial stages ● Discontinue modeling when the client gives five consecutively correct, imitated responses ● Reinstate modeling if errors persist ● Consider an exemplar of a target behavior trained when the client gives 10 consecutively correct responses ● Consider a behavior tentatively trained when the client gives 90% correct responses on untrained exemplars on an intermixed probe ● Consider a behavior trained when the client gives 90% or better correct responses in conversational speech produced in extraclinical situations
Cued Speech. A system of nonverbal communication that is used as a supplement to speech reading; consists of eight hand shapes that represent categories of consonants and four positions about the face that represent categories of vowels; these hand shapes and positions suggest speech sounds in running speech; known to promote better reading skills in children who are deaf.
Cultural Diversity and Treatment Procedures. Factors related to ethnic background, culture, and linguistic 167

status that may influence treatment outcome; factors to be considered in planning treatment for individual clients; see Ethnocultural Variables in Treatment.
Cysts. Acquired or congenital, fluid-filled lesions of the larynx caused by trauma; can occur contralaterally to a unilateral Vocal Nodule; usually unilateral; treatment is surgery.
168
169
Deaf Deaf.
D
A person whose hearing impairment is severe enough to prevent normal oral language acquisition, production, and comprehension with the help of audition; profound hearing loss that exceeds 90 dB HL; see Hearing Impairment for rehabilitation.
Deblocking. A technique used in treating clients with aphasia; uses an intact response to one kind of stimulus to deblock a deficient or absent response to another kind of stimulus (e.g., visual stimuli to which the client responds appropriately may be used in promoting a deficient or nonexistent response to auditory stimuli; for the procedure, see Aphasia, Treatment; Treatment of Naming: Targets and Techniques.
Dedicated Systems of Augmentative Communication. Computers designed and built exclusively for augmentative communication; see Augmentative Communication.
Deglutition. Swallowing; see Dysphagia for normal and abnormal swallow.
Delayed Auditory Feedback (DAF). A procedure in which a speaker’s speech is fed back to his or her ears through headphones after a delay; most speakers slow their speech down under DAF; technique is used in reducing the speech rate in persons who stutter or clutter and those who have dysarthria; see Cluttering; Dysarthria; Stuttering; Treatment of Stuttering: Specific Techniques or Programs. ● Select one of the several DAF machines available on the market ● Experiment with different durations of delay that induce speech that is free from stuttering or cluttering or speech rate that improves intelligibility in dysarthric speakers ● Train and stabilize the target speech skills with the selected delay ● Fade DAF and shape the normal rate and prosody
170
Deletion Processes Deletion Processes. A group of phonological processes in which one or more consonants or a syllable in a word is deleted or omitted; in phonological treatment, the target is to eliminate such processes; major deletion processes include: ● Cluster reduction: one or more consonants are deleted in a cluster of consonants (e.g., bu for blue) ● Initial consonant deletion: omission of an initial consonant of a syllable (e.g., ink for sink) ● Final consonant deletion: omission of a final consonant (e.g., goo for good) ● Unstressed syllable deletion: omission of a syllable (e.g., medo for tomato, nana for banana)
Demands and Capacities Model (DCM). A theory of stuttering which states that when the environmental demands made on a child to produce and sustain fluency exceeds the child’s capacity to do so, stuttering results; treatment involves reducing the demands and gradually increasing the child’s fluency skills; for procedures see Stuttering, Treatment; Treatment of Stuttering: Specific Techniques or Programs; Stuttering Prevention: A Clinical Method.
Dementia.
An acquired neurological Syndrome associated in most cases with persistent or progressive deterioration in intellectual and communicative functions and general behavior; sustained over a period of months or years; examples include dementia due to Alzheimer’s Disease, Huntington’s Disease, Parkinson’s Disease, or vascular disease; dementia is static in a few cases and reversible in 10 to 20% of the cases; in most cases, treatment is concerned with behavioral and clinical management because the disease is progressive and the effects irreversible; both the client and his or her family need treatment.
Counsel and Educate the Family Members Dementia affects family as much as it affects the persons who have it; therefore, counseling the family and finding

them emotional, financial, and professional support are important. ● Educate the family members about: • the causes, symptoms, and course of dementia • the specific type of dementia and its neurological basis • general medical and behavioral management procedures ● Give family members a realistic picture of what is ahead; discuss with them the need to cope with a difficult, prolonged, and expensive problem, the nature or even existence of which may not be understood by the patient himself or herself, especially in later stages ● Tell them that that as time passes, they are most likely to be concerned with and troubled by the patient’s: • physical violence • memory deficits • catastrophic reactions • incontinence • delusions and hallucinations • making accusations and suspiciousness • uncooperative at bathing and at mealtime • communication problems • demanding, critical behaviors • unsafe driving, cooking • hiding things • daytime wandering and night walking ● Let them understand that patients with dementia, especially in the beginning states, are frustrated, worried, anxious, and angry ● Let them understand that in due course, the patient is likely to be depressed and may withdraw from the family ● Prepare the family members for: • potential emotional outbursts and angry exchanges over trivial matters 172

• abusive, aggressive, and violent behaviors in later stages • constant supervision or institutionalization of the patient in the later stages of dementia • the eventual need to feed, clothe, and take care of the person in all respects, including oral hygiene • the eventual incontinence that will increase the burden of care tremendously • extended period of home care (1 to 2 years to 10 to 15 years) • needing emotional, social, financial, and psychological help for themselves, not just the patient Impress upon the family members that rehabilitative efforts are still very important to slow down the process of deterioration in the physical, social, and intellectual status of the person with dementia Help the family members cope financially with the long-term care of the patient with dementia: • let them appreciate the long-term cost and efforts involved in managing a person with dementia • discuss the family’s available resources to care for and pay for the services • help them find and contact local, state, and federal agencies along with private sources that offer financial support to families who have a patient with dementia Offer them help in finding appropriate nursing home placement when the time comes Give them consumer-oriented printed information on dementia and its management Give them names and addresses of local professional and social associations and organizations concerned with aging and dementia Introduce them to local support groups Give them information on any accessible specialty clinics, research centers, and universities where unique programs are being evaluated 173
D
Dementia: Clinical Management ● Give them information on websites that offer sugges-
D
tions, newsletters, and information on new developments in medically or behaviorally managing persons with dementia ● If not already served by a team of specialists, including those who can counsel the family members (e.g., psychiatrists, psychologists, and social workers), make referrals ● Arrange for the team to help the family members make rational and acceptable decisions about making or not making heroic efforts to sustain life in the terminal stage of dementia ● Arrange for continued counseling after the demise of the patient to help the family members regain their energies, rebuild deteriorated relationships among surviving members, deal with grief and loss, and manage financial burden of extended care
Clinical Management of Patients With Dementia. Design a program to help the person with dementia sustain skills and behaviors to the extent possible; cope with progressive deterioration in skills and behaviors; teach compensatory strategies. ● Establish a simple routine for the patient and the family ● Manage the patient’s memory problems; design such stimulus control procedures as reminders, prompters, pictures, lists, and other devices to manage the memory problems; but include systematic training to use them; note that differential reinforcement is important to make stimulus manipulations work for the patients; see also Memory Impairments: • note that external cues are more effective than internal cues (self-monitored) in improving memory skills, although teaching self-monitoring skills is recommended • note that any kind of prompt that reminds the patient of an activity or encourages a patient to do something is better than no prompts 174
Dementia: Clinical Management • give verbal prompts that remind patients of scheduled activities (e.g., a social gathering, a game, a party), which may be more effective than other kinds of reminders (e.g., a bright poster printed in large letters) • note that just making materials and opportunities for activities may not be sufficient to prompt actions and activities; patients need verbal prompts and reinforcement for following through • reinforce institutionalized patients for paying attention to reminders, signs, posters, announcements, and scheduled activities as these may not be effective without such reinforcement • train patients by reinforcing them to use, and prompt them to consult, a diary that they keep about appointments and schedules of events because it is not sufficient to have them simply write them down on a piece of paper • have caregivers in an institution wear name tags printed in larger letters, train the caregivers to draw attention to their name tags, and have patients read them or caregivers read them aloud; train the caregivers to reinforce the patients for saying the name or reading it aloud • have patients keep a list of activities that are more immediate (i.e., today’s activities as against this month’s activity), and train caregivers to prompt the patient to consult the list at appropriate times • teach the client to use portable alarms that remind him or her of appointments and scheduled activities; monitor the use of the devices and reinforce the patient for maintaining this skill • give written instructions on daily living chores (closing the windows, locking the doors, turning the stove off); teach the client to follow the instructions and reinforce him or her for doing so 175

• train staff members in health care facilities to give frequent and systematic reminders to the clients and to reinforce the client in appropriate ways for exhibiting the required skills or following directions • teach the client to rehearse information (e.g., just before leaving, rehearsing the names of people to be encountered in a party or class reunion; visualizing the faces of people to be encountered) • teach the client to self-monitor; reinforce the client for doing this and evaluate its maintenance • create a naming wallet containing pictures of family members, their names, and sentences and phrases about them, and train the patient to carry it and use it Teach clients to make a written list of what to do every day; train the client to use the list by frequent prompts and positive reinforcements Teach the client to keep personal belongings (keys, clothing items, eye glasses, pens) in a specific, invariable place; frequently monitor and reinforce this skill Teach the client to keep related objects together (e.g., paper and pencil; socks and shoes; coffee and sugar); frequently monitor and reinforce this skill Train the client to carry a card that contains the name, address, telephone number of a family member and a health care professional; frequently check the client to see if this is maintained Teach the client to wear a bracelet that contains personal identification; check its continued use Instruct the client to exploit his or her strengths to compensate for weaknesses (e.g., writing down everything when memory tends to fail) Teach clients to ignore relatively minor problems (e.g., word-finding difficulties) Teach the client to take enough rest so fatigue will not further complicate the condition Control disorientation and confusion 176
Dementia: Clinical Management • place a large calendar in the patient’s bedroom and cross off the current date every night; draw the patient’s attention to this activity and tell the patient what you are doing (remember, that you are not doing it for your benefit) • make the patient wear a digital calendar watch with large display of AM and PM, date and day; frequently draw attention to it; have the client use it in realistic situations (e.g., instructing the patient to look at the watch and saying that it is now 12 noon and time to have lunch) • provide maps of frequently visited places (e.g., homes of relatives or friends, doctor’s office, shops, favorite restaurants); before visiting the places, prompt the patient to consult the maps ● In treating communication disorders in early stages of dementia, provide cues to evoke words and then teach self-cueing techniques; see Aphasia for details and additional examples: • give phonemic cues for words (e.g., the clinician says ‘‘The word starts with an s’’ to evoke spoon) • give such semantic cues as a generic class (e.g., the clinician says ‘‘woman’’ to evoke the word ‘‘wife’’); a synonym (e.g., the clinician says ‘‘dwelling’’ to evoke ‘‘house’’); an antonym (e.g., the clinician says ‘‘good’’ to evoke ‘‘bad’’); a category name (e.g., the clinician says ‘‘it is a fruit’’ to evoke ‘‘apple’’); or an associated word (e.g., the clinician says ‘‘cup’’ to evoke ‘‘plate’’) • train the patient to use description as cues in which he or she describes an object before naming it • teach self-cueing by having the client produce the successful cues to generate the intended word • note that contingent consequences (positive reinforcement and corrective feedback) are known to be effective in modifying communicative behaviors in patients with dementia 177
D
Dementia: Clinical Management
D
• ask orientation questions (questions about time and place), model the correct responses, and verbally reinforce the patient for imitating the correct responses; gradually fade the modeling and have the patient respond to questions • train the patients to initiate conversation and reinforce them for doing so • ignore inappropriate, irrelevant, vulgar, delusional, and any other type of unacceptable or bizarre verbal behaviors and reinforce any appropriate verbal responses (differential reinforcement) • reinforce the patients continuously (reinforcement for all desirable responses); if needed, reinforce the patients with tangible reinforcers ● To sustain social and communicative skills as long as possible, arrange group therapy sessions involving family members or other patients with similar problems; direct the sessions and manage the behavioral contingencies to promote the selected goals of the group session; provide refreshments during these sessions, as some data suggest their potentially positive effects on interaction; arrange the sessions to have the patients: • tell stories in group sessions • maintain topics of conversation • take appropriate turns in conversation • express their own feelings and thoughts about their disease • arrange for generous verbal reinforcers for all targeted expressions and any other appropriate expressions • ignore and teach the group members to ignore inappropriate responses ● Sustain skills as long as possible, even if they have to be progressively simplified: • encourage the patient to continue to cook but with support • arrange for cooking simpler foods 178
Dementia: Caregiver Strategies • sustain reading skills with routine materials (e.g., TV listings, newspapers, labels on packaged foods, restaurant menus) • get the patient involved in social activities and family group activities as long as possible • provide plenty of verbal reinforcement for the patient’s effort to sustain skills and social behaviors
Management Strategies for Patient’s Caregivers, Including Family Members. Family members and other caregivers need help in managing persons with dementia; ask all those who care for and regularly interact with the client to: ● Be observant about changes in the patient’s behavior that might signal a significant change in health status ● Take steps to sustain the patient’s physical health by making sure that the patient: • regularly takes the prescribed medications • eats properly • exercises regularly ● Be consistent ● Reduce distractions ● Design and maintain a consistent routine for the patient ● Reassign household chores the patient cannot perform anymore, but do not expropriate the patient’s responsibilities too soon ● Design and maintain a constant and simplified environment ● Make environmental modifications that support communication and help prevent social isolation and more rapid deterioration in behavior, including communication: • create and maintain communication opportunities for the patient • incorporate as much relevant speech as possible with daily routines • do not restrict expression and communication with the fear that the patient may be irrelevant 179
D
Dementia: Caregiver Strategies
D
• remove unduly restrictive rules against talking and social interactions in institutional settings • find regular conversational partners for the patient at home and in institutional settings; recruit friends, grandchildren, family members who do not see the client regularly, neighbors, former colleagues, and volunteers (especially in an institution) • help the patient maintain contact with grandchildren and other younger acquaintances; work with both the younger persons and the patient to foster this relationship • encourage patients to observe social activities even if they do not participate in them • encourage patients in the early stage of dementia to offer help in some designated activities to their spouses and other family members at home or other patients in institutions (e.g., helping spouses in cooking, cleaning, or shopping; helping new patients with routines in an institution) • arrange regular small group activities at home; facilitate and reinforce the patient’s participation • let the patient have a say in arranging or rearranging his or her personal space (room design, color, furniture, decorations) • encourage the patient to be responsible for maintaining his or her personal space for as long as possible • allow the patient some privacy (do not relentlessly supervise when it is unnecessary) • use contrasting colors to enhance orientation to hand rails, hallways, communication boards, table settings, and room decorations; note that just these measures may not promote appropriate behaviors; train the patient to make use of them • pay attention to the patient’s ethnocultural background in arranging his or her environment
180
Dementia: Caregiver Strategies • pay attention to the patient’s ethnocultural background in arranging conversational partners and topics • pay attention to a bilingual patient’s primary language or the dominant language in arranging communication opportunities and topics; find interpreters or similarly bilingual conversational partners • have family members regularly visit the institutionalized patient • have family members participate in social events at the institution • have family members take part in social activities arranged at the institution ● Attend to the sensory needs of the patient, especially in the early and middle stages of dementia: • have the client’s vision checked and provide new glasses if need • provide magnifying glasses and printed material with larger print to sustain reading skills • place all visual information at the patient’s eye level • keep the patient’s living environment visually attractive • have the client examined by an otologist and take necessary steps to maintain the patient’s otological health • have the client’s hearing checked by an audiologist and provide hearing aids as recommended • monitor the use of hearing aids on a daily basis, as assistance may be needed in inserting and removing the hearing aids and in volume adjustments • discuss with an audiologist the need for Assistive Listening Devices described under Aural Rehabilitation and follow the recommendations • reduce or eliminate noise in situations where communication takes place (e.g., turn off the TV or radio while talking to the client; monitor such mechanical noises as those of air conditioners and fans)

• evaluate whether the patient whose visual and auditory acuity is diminished reacts better to improved tactile and olfactory cues Approach the client slowly, with calm and inviting expressions, and within his or her visual field (do not surprise the patient) Establish eye contact before speaking Let the patient see your face clearly while talking (stoop down if the patient is in a wheelchair) Supplement speech with gestures, smiles, and posture Speak clearly and directly Speak in simple terms Use requests instead of commands (e.g., ‘‘Should we do this together?’’ or ‘‘Would you give me a hand and help?’’) Specify referents for speech (e.g., ‘‘We need to go to the dining hall’’ instead of ‘‘We need to go over there.’’); use proper names (e.g., your wife Jane, physical therapist Tom) instead of pronouns (e.g., he, she, they) Have only one or two people engage the client in conversation at any one time Do not argue with the patient; instead rearrange the environment (e.g., do not try to convince a suspicious person with arguments that no one has taken his or her possessions; instead, make sure that the possessions are always kept in one predictable, easily accessible place) Record problems that occur with a view to find patterns in them; design strategies to control them (e.g., an episode of aggressive behavior may have been triggered by physical pain that may need medical attention) Ask yes/no questions Ask either/or questions Ask short questions Ask simple questions
182
Dementia: Caregiver Strategies ● Be specific in your communication with the patient ● Avoid vague references, sarcasm, indefinite referents,

Demonstration. A stimulus procedure used in treatment; usually preceded by instructions on how to produce a target response. ● Describe the target behavior the client is expected to produce
185
D
Denasality (Hyponasality) ● Model the response for the client ● Show how the response is produced (e.g., how /k/ is
D
produced)
● Give maximum feedback (use a mirror if necessary) ● Reinforce the correct response or an approximation of it
Denasality (Hyponasality). Lack of nasal resonance on nasal sounds; a disorder of resonance associated with various voice disorders and cleft palate; see treatment procedures under Voice Disorders and Cleft Palate.
Dependent Variables. Effects of causes studied by scientists; target behaviors taught to clients and pupils; contrasted with Independent Variables.
Deteriorating Baselines. Baselines of a progressively worsening problem; desirable behaviors (e.g., fluency) that are lower each time they are measured; require immediate treatment; an exception to the rule that in a treatment evaluation study, intervention should be started only after baselines are stable. ● Measure baselines repeatedly ● If the desirable behavior shows a consistent worsening (or the undesirable behavior shows a consistent increase) across baseline sessions, initiate treatment immediately
Determinism. A philosophical position that nothing happens without a cause; basis of modern science, whose goal is to explain events by finding their causes.
Developmental Apraxia of Speech (DAS). A speech disorder in children that shares some common characteristics with Apraxia of Speech (AOS) in Adults, but without documented neuropathology; primarily an articulatory (phonologic) disorder characterized by sensorimotor problems in positioning and sequentially moving muscles for the volitional production of speech; associated with prosodic problems; not caused by muscle weakness or neuromuscular 186
Diagnosis slowness; presumed to be a disorder of motor programming for speech; controversial because of the absence of neuropathology; little or no controlled treatment efficacy data; most treatment programs are only suggestive.
Motor-Programming Approaches
● Plan on providing intensive treatment to children with DAS ● Use multiple repetitions of speech movements ● Use extensive drill; stress sequence of movements in-
volved in speech production
● Determine the need for auditory discrimination training ● Progress hierarchically from easy to difficult tasks
● ● ● ●
●
• determine at what level the child will respond (phonemes, syllables, words) • concentrate on vowels and consonants that children produce early • teach consonants that are visible • teach phonemes that occur often • teach voiceless consonants before voiced consonants Provide multimodality input on sound productions (visual, auditory, kinesthetic, tactile) Teach Self-Control (Self-Monitoring) Skills Reduce the speech rate if necessary Manipulate prosodic features within the treatment program; use such programs as Contrastive Stress Drills; if necessary increase pause durations between words Use techniques of treating Articulation and Phonological Disorders

Diagnosis. A clinical activity designed to find causes of diseases or disorders, especially in medicine; in communicative disorders, diagnosis often is aimed at describing and assessing the degree of severity of disorders; requires precise and reliable measurement of communicative behaviors; often means the same as Assessment; see the cited sources and PGASLP for details on assessing various disorders of communication. 187

Dialect. A spoken form of a language with its own phonologic, semantic, grammatic, and pragmatic properties and rules; any variation of a language; a variation may be considered standard although all variations are acceptable forms of communication; in a bilingual speaker, may be influenced by the primary language; not a basis to diagnose a disorder; see Ethnocultural Variables in Treatment.
Differential Reinforcement. (a) The method of establishing discriminated responding by reinforcing a response in the presence of one stimulus and not reinforcing the same response in the presence of another stimulus; (b) an indirect method of response reduction by increasing another, desirable behavior; specific techniques include Differential Reinforcement of Alternative Behaviors (DRA), Differential Reinforcement of Incompatible Behaviors (DRI), Differential Reinforcement of Low Rates of Behaviors (DRL), and Differential Reinforcement of Other Behaviors (DRO).
Differential Reinforcement of Alternative Behaviors (DRA). One of the Indirect Methods of Response 188
DRI Reduction in which an undesirable behavior is reduced by reinforcing a specified desirable behavior that serves the same function as the one to be reduced; also known as Functional Equivalence Training. ● Find out what function (purpose) the undesirable behavior to be reduced seems to serve (e.g., fussing in treatment sessions may mean that the child finds the task too difficult and cannot request help) ● Select a behavior that is a desirable alternative to the behavior to be reduced (e.g., the response ‘‘help me,’’ if the child could make it, may serve the same function as fussing) ● Reinforce the production of the alternative, desirable response (e.g., teach the child to say ‘‘help me’’ instead of fussing)
Differential Reinforcement of Incompatible Behaviors (DRI). One of the Indirect Methods of Response Reduction in which an undesirable behavior is reduced by reinforcing a behavior that is incompatible with the behavior targeted for reduction. ● Specify the behavior to be reduced (e.g., leaving the chair and walking in the therapy room) ● Specify a behavior that is incompatible (e.g., sitting quietly and looking at the stimulus items presented) ● Systematically reinforce the child (for sitting quietly and looking at the stimulus items) ● Suspend training on the target communicative skill for a while if necessary and until the sitting behavior is stabilized
Differential Reinforcement of Low Rates of Responding (DRL). One of the Indirect Methods of Response Reduction in which an undesirable behavior is reduced by reinforcing its progressively lower frequency of occurrence; the method shapes down an undesirable behavior. 189
D
DRO ● Specify the undesirable behavior to be reduced (e.g., inter-
rupting treatment by irrelevant questions)
D
● Specify an acceptable level of the undesirable behavior
(e.g., two questions in a 10-minute period)
● Reinforce the client for not exceeding the set level (‘‘Good!
You asked only two questions during the last 10 minutes!’’)
● Specify a new, more stringent criterion in successive stages
until the behavior is eliminated or kept to a minimum
Differential Reinforcement of Other Behaviors (DRO). One of the Indirect Methods of Response Reduction in which an undesirable behavior is reduced by reinforcing any one of many unspecified behaviors; the behavior that will not receive reinforcement is clearly stated. ● Specify the undesirable behavior to be reduced (e.g., leaving the chair and walking around) ● Tell the client that he or she will not receive reinforcers for that behavior; also say that he or she will receive a reinforcer as long as the undesirable behavior is not exhibited ● Periodically reinforce the child for not exhibiting the undesirable behavior (perhaps for sitting quietly, reading, coloring, working on other assignments, but none specified as the response to be reinforced)
Digital Manipulation. Physical manipulation of the larynx during voice therapy; for the procedure, see Voice Disorders: Specific Normal Voice Facilitating Techniques.
Diplophonia.
Double voice resulting from differential vibration of the two vocal folds or vibration of both the true and false vocal folds.
Direct Language Treatment Approaches. Clinicianplanned and implemented language treatment with specified target behaviors; structured treatment sessions; requirement that the child first imitate and then spontaneously produce the selected target behaviors; described under Language Disorders in Children; Treatment of Language Disorders: Specific Techniques or Programs. 190
Direct Methods of Response Reduction Direct Methods of Response Reduction. Procedures to reduce undesirable behaviors by directly placing a contingency on them; contrasted with Indirect Methods of Response Reduction. ● Specify the undesirable behavior to be reduced ● Place one of the following contingencies on it: • Corrective Feedback (e.g., say ‘‘No’’) • Time-Out (say ‘‘Stop,’’ turn your face away for 5 seconds and then reestablish eye contact and resume conversation) • Response-Cost (take back a token contingent on every incorrect response) • Extinction (ignore the response) • Imposition of Work (ask a child who disrupts your stimulus materials to organize them for you)
Direct Stuttering Reduction Strategies. Treatment techniques that reduce stuttering by placing behavioral contingencies directly on stuttering itself; includes time-out (pause-and-talk) and response cost; see Stuttering.
Direct Treatment for Swallowing Disorders. Treatment of swallowing disorders by feeding the patient small amounts of food or liquid; see Indirect Treatment for Swallowing Disorders.
Disability. A person’s inability to perform an action that is normally expected of that person; a term so defined in the World Health Organization’s International Classification of Impairments, Disabilities, and Handicaps.
Discrete Trials.
Structured treatment or probe trials that are temporally separated providing discretely measured opportunities for producing responses; useful in establishing target skills but not efficient in promoting generalized and maintained production; include Baseline Evoked Trials, Baseline Modeled Trials, Treatment Evoked Trials, and Treatment Modeled Trials; the general structure of a discrete trial includes the following steps: 191
D
Discrimination ● Present a physical stimulus to evoke a response (e.g., a
picture, an object)
D
● Ask a question that evokes a response (e.g., ‘‘What is
this?’’)
● Model the correct response initially; fade the modeling
gradually (e.g., ‘‘Johnny, say I see a rabbit’’ on the initial trials and just the question on later trials) ● Reinforce the correct response and give corrective feedback for incorrect responses ● Move the stimulus away from the client ● Record the response as correct, incorrect, absent, and so forth ● Wait for a few seconds to mark the end of a trial ● Represent the stimulus and start a new trial ● Adapt this basic structure to suit the different target behaviors that are taught with discrete trials Discrimination. A behavioral process of establishing different responses to different stimuli; opposite of generalization; needed to teach such discriminated responding as plural words to plural stimuli and singular words to singular stimuli. Distinctive Features. Unique characteristics of phonemes that distinguish one phoneme from the other; the system is binary in that a feature is scored as 1 if it is a characteristic of a phoneme and as 0 if it is not; may be used in economically describing errors of articulation and their changes in treatment (see treatment of Articulation and Phonological Disorders: Treatment of Articulation and Phonological Disorders: Specific Techniques or Programs); Chomsky-Halle’s major distinctive features include the following: ● Vocalic: Sounds produced without a marked constriction of the vocal tract; all vowels and the consonants /l/ and /r/ ● Consonantal: Sounds produced by vocal tract constriction; all consonants except for /h/, /w/, and /j/ ● High: Sounds produced with elevated tongue position; include /ʃ/, //, /tʃ/, /d/, /k/, /g/, and /ŋ/ 192
Dysarthria ● Back: Sounds produced with tongue retracted; include /k/,
/g/, and /ŋ/
● Low: Sounds produced with lowered tongue position;

General Treatment Procedures. Because of the variability of dysarthria, its subclassifications, and varied neuropathology, select a particular treatment target and strategy only when a careful assessment of the client’s clinical problems justifies it; some techniques produce temporary effects; others are contraindicated for certain clients; many are suggested based on clinical experience and lack controlled experimental evidence to support their routine use; continue to use a technique only when it produces a clear and positive effect on the client’s behavior; abandon ineffective procedures and modify those that seem to hold promise. Modification of Respiration ● Train consistent production of subglottal air pressure; use manometer or air pressure transducer ● Train maximum vowel prolongation ● Shape production of longer phrases and sentences ● Teach controlled exhalation ● Teach sustained exhalation throughout utterances ● Teach pausing and breathing at appropriate junctures in speech ● Teach client to push, pull, or bear down during speech or nonspeech tasks ● Use manual push on abdomen ● Find a normal or an unusual posture that promotes respiratory support and teach it (e.g., some clients’ speech improves in supine position) ● Let the client use neck and trunk braces if helpful ● Use adjustable beds and wheelchairs to make postural adjustments ● Use girdles and wraps around the abdominal area to increase muscle strength for respiration ● Use an Expiratory Board to stabilize the abdominal muscles for respiration 196
Dysarthria: General Treatment ● Teach the client to inhale more deeply and exhale
slowly and with greater force during speech
● Train the client to terminate speech earlier during
exhalation Modification of Phonation ● Discuss with medical staff the need, effects, and effectiveness of medical treatments including Laryngoplasty, Teflon or Collagen Injection, Recurrent Laryngeal Nerve Resection, Botulinum Toxin Injection, and pharmacological measures; consider them in the total management of the client and in treating communication disorders ● Use biofeedback devices to give the client immediate feedback on vocal intensity to effect changes in excessive or too little loudness ● Train the client with a too soft voice in using a portable amplification system ● Train aphonic clients in the use of Artificial Larynx ● Ask clients with aberrant neck movements or neck muscle weakness to wear Neck Braces ● Teach Effortful Closure Techniques for clients with vocal fold paralysis (e.g., pulling or pushing while phonating) ● Teach the client to initiate phonation at beginning of exhalation ● Teach the client to turn head toward weak side during speech; try digital manipulation of the thyroid cartilage to increase loudness; be aware of temporary effects of these ● Try relaxation exercises and laryngeal massage to increase loudness ● Teach the client to tilt head back, initiate speech after a deep inhalation, and increase pitch to reduce strained voice quality ● Teach the client with vocal fold hyperadduction to initiate phonation with breathy onset or a sigh 197

Treatment of Dysarthria: Specific Types.
In planning treatment for a client with dysarthria, consider first the general guidelines and procedures described in the previous section along with those that follow for specific types. If a definitive diagnosis of a particular type is not made, carefully evaluate the communicative deficits and design a treatment program to remediate or modify targeted deficits. Ataxic Dysarthria. A type of motor speech disorder; its neuropathology is damage to the cerebellar system; characterized by slow, inaccurate movement and Hypotonia; all aspects of speech may be involved, but articulatory and prosodic problems dominate; specific symptoms include imprecise consonants, excess and equal linguistic stress, and irregular articulatory breakdowns; select appropriate treatment targets and procedures described under Dysarthria; in addition, consider the following that apply especially to ataxic dysarthria: ● Use behavioral methods of Shaping and Differential Reinforcement to improve control and coordination ● Do not concentrate on increasing muscle strength or reducing muscle tone ● Do not recommend prosthetic or surgical methods to improve phonation or resonance ● Modify respiratory problems associated with speech production: • teach the client to inhale more deeply and exhale in a slow and controlled manner to sustain speech 201
D
Dysarthria: Ataxic
D
• measure the duration of exhalation and reinforce progressively longer (more controlled) exhalation • teach the client to begin speaking soon after the start of exhalation to avoid wasting airflow; reinforce prompt phonation upon initiation of exhalation • teach the client to end an utterance well before running out of air; stop the client when signs of airflow dissipation are evident, and ask the client to breathe in again • teach the client to stop and inhale at natural junctures in a sentences (e.g., at the beginning of a grammatical clause) ● Modify prosodic problems that result mostly from irregular, slow, or even rapid rate of speech: • slow the rate of speech with the help of metronome beats • use finger or hand tapping to generate an even and appropriate rate of speech • provide such cues as pointing to a printed word to generate an appropriate and even oral reading rate • teach appropriate stress on words in sentences; use contrastive stress exercises • teach variations in pitch by using both printed sentences and conversational speech • control excess loudness variation by reinforcing normal variations ● Modify articulation problems that may persist even at slower rate of speech: • ask the client to produce words on a list while you judge their intelligibility while not looking at the list or the client’s face • give corrective feedback to encourage appropriate production of sounds in words you do not understand
202
Dysarthria: Flaccid • teach correct production of sounds by using the Phonetic Placement Method • reinforce overarticulation or exaggerated articulation of medial and final consonants • use the Minimal Contrast Method, to improve intelligibility of words that differ by only one phoneme ● Reinforce more natural sounding conversational speech ● Implement a Maintenance Strategy to train family members and other caregivers who will help sustain treatment gains Duffy, J.

Flaccid Dysarthria. A type of motor speech disorder; its neuropathology is damage to the motor units of cranial or spinal nerves that supply speech muscles (lower motor neuron involvement); flaccidity (hypotonia) and weak muscle contractions are dominant neurological symptoms; speech problems caused mostly by muscle weakness and Hypotonia; constellation of speech disorders dependent on the specific nerve or nerves that are affected, but include breathy and harsh voice quality, hypernasality, nasal emission, imprecise production of consonants, audible inspiration, monopitch and loudness, and short phrases; select appropriate treatment targets and procedures described under

Dysarthria; in addition, consider the following that apply especially to flaccid dysarthria: ● Make a thorough assessment of dysarthria and the associated neurological and physical conditions the client presents; consult the sources cited and the PGASLP ● Improve muscle strength and range of motion. Note that exercises to strengthen speech-related muscles are controversial; some recommend it whereas others consider it a waste of time because speech requires only a small amount of muscular force; may be recommended for clients with severe dysarthria; exercises that involve muscle movement (isotonic exercise) may be more beneficial than those that ask the client to exert force against stationary resistance (isometric exercise). Also, muscle strengthening work that involves speech production may be more effective than those that do not involve speech production. Nonetheless, various suggestions to strengthen muscles and their range of motion include the following: • try to increase muscle strength by asking the client to increase effort while speaking; may be sufficient in some cases • strengthen the jaw muscles by asking the client to several times open and close the jaw as fully as possible; manually push the jaw upward while the client tries to open it or hold the chin down while the client tries to close the jaw; these may be beneficial in the case of flaccid dysarthria caused by damage to trigeminal cranial nerve V • strengthen lip muscles by asking the client to resist as you pull a string attached to a button placed behind the client’s closed lips and against the central incisors; ask the client to pucker the lips firmly and hold it for several seconds; ask the client to smile widely and hold it for several seconds; these 204
Dysarthria: Flaccid may be beneficial in the case of flaccid dysarthria caused by damage to facial cranial nerve VII • increase overall muscle tone by asking the client to push down on the arms of a chair • increase tongue strength (perhaps the most controversial of all muscle strengthening exercises) by having the client (a) push the tongue out; (b) push the tongue to one or the other side; (c) lift the tongue tip; and (d) lift the back of the tongue as you apply resistance with a tongue blade to oppose the client’s effort in each case; may be beneficial in case of flaccid dysarthria caused by damage to hypoglossal cranial nerve XII ● Modify respiratory behaviors • use pushing/pulling exercises to increase respiratory support • make postural adjustments by asking the client to sit straight in the chair to increase breath support for speech • place a padded lap tray on the wheelchair, positioned next to the abdomen and ask the client to lean against it to increase breath support • teach the client to phonate at the beginning of exhalation to conserve air supply for speech • teach the client to inhale deeply and exhale in a controlled manner • increase breath group durations • increase the number of words per breath group ● Modify phonatory problems • increase loudness by modeling louder speech and reinforcing increase in client’s vocal loudness; use computer programs to give feedback on loudness • consider Teflon/collagen injections to improve vocal fold adduction • teach pushing and pulling while speaking to promote better approximation of vocal folds 205
D
Dysarthria: Flaccid
D
• ask the client to inhale deeply and hold the breath to promote firmer approximation of folds • ask the client with a unilateral vocal fold weakness or paralysis to turn head toward the affected side or manually push the larynx toward the unaffected side to help achieve better closure ● Modify resonance problems • note that hypernasality is the main resonance problem caused by damage to the pharyngeal branch of the vagus nerve; the soft palate may be weak or paralyzed • discuss the suitability of the Pharyngeal Flap Operation with a surgeon to improve velopharyngeal closure; note that the results have been inconsistent • discuss the suitability of Pharyngoplasty with a surgeon to improve velopharyngeal closure; note that the results have been inconsistent • recommend Palatal Lift Prosthesis, as this has been more effective in reducing hypernasality than pharyngeal flap or pharyngoplasty; note that this device is most effective with clients who (a) are severely hypernasal and have not improved with behavioral treatment; (b) do not have spastic velopharyngeal mechanism which may dislodge the device; (c) have teeth for anchoring the device; (d) have good articulation and phonation without which the device will not improve speech intelligibility; (e) do not have hyperactive gag reflex or swallowing problems; and (f) are motivated to wear it and care for it • use behavioral methods if hypernasality is mild; shape progressively less hypernasal voice by modeling and positive reinforcement and corrective feedback
206
Dysarthria: Flaccid ● Modify articulatory problems
• reduce the rate of speech to improve speech intelligibility (and to some extent, hypernasality); use finger tapping to cue a slower rate by having the client produce a syllable or a word per a tap; give frequent instructions to slow down and reinforce the desired rate • teach better articulatory skills by reinforcing improved articulation of speech sounds; use a systematic approach of modeling and reinforcing correct articulation in words, phrases, sentences, and conversational speech • if preferred, use the Intelligibility Drills in which the client reads aloud a list of words when the clinician has turned his or her back; when the clinician does not understand a word , he or she will turn around to face the client, analyze the errors, give suggestions on correct productions, and reinforce correct productions • use Phonetic Placement Method to teach correct placement of articulators in producing target sounds • teach exaggerated production of consonants to improve speech intelligibility; ask the client to fully articulate consonants, especially in medial and final positions of words • use the Minimal Contrast Method to further improve articulation ● Modify prosodic problems • note that pitch, stress, and rhythm deviations contribute to an abnormal prosody in clients with flaccid dysarthria • ask the client to discriminate pitch changes as you model different levels of pitch • ask the client to prolong an /a/ with lower and higher pitch

Hyperkinetic Dysarthria. A type of motor speech disorder; its neuropathology is damage to basal ganglia (extrapyramidal system), resulting in rapid involuntary movements and variable muscle tone; may affect all aspects of speech, but a dominant symptom is prosodic disturbances; specific problems include prolonged intervals, variable rate, monopitch, loudness variations, inappropriate silences, imprecise consonants, and distorted vowels; most effective treatment is medical; various medications help control involuntary movements; for communication treatment, select appropriate treatment targets and procedures described under Dysarthria; in addition, consider the following that apply especially to hyperkinetic dysarthria: 208

Hypokinetic Dysarthria. A type of motor speech disorder; its neuropathology is damage to basal ganglia (extrapyramidal system) resulting in slow movement, limited range of movement, and rigidity; parkinsonism is the most frequent cause of this type of dysarthria; may affect all aspects of speech, but especially voice, articulation, and prosody; specific problems include monopitch, monoloudness, reduced stress, imprecise consonants, variable rate of speech, increased speech rate in some cases and a slower rate in a few, short rushes of speech, inappropriate silences, and harsh and breathy voice. Select appropriate treatment targets and procedures described under Treatment of Dysarthria; in addition, consider the following that apply especially to hypokinetic dysarthria: ● Make a thorough assessment of dysarthria and the symptom complex that justifies the diagnosis of hypokinetic dysarthria; consult the cited sources and PGASLP ● Modify respiratory behaviors by teaching the client to: • inhale deeply before speaking • start speaking when inhalation begins • exhale slowly and in a controlled manner • stop talking well before exhausting the air supply • gradually increase the number of words spoken per breath ● Modify phonatory problems • use voice therapy techniques to increase vocal loudness and to decrease breathiness; use various biofeedback instruments (e.g., the VisiPitch) 210
Dysarthria: Hypokinetic • use pushing and pulling techniques to increase the movement range of laryngeal muscles (e.g., having the client push down on the arm of the chair while phonating) • use portable voice amplifiers to increase loudness ● Modify articulatory problems • use rate-control for clients who speak rapidly; use hand or finger tapping to cue-in production of syllables or words; use delayed auditory feedback to slow down the rate; use a metronome to have the client pace syllable or word productions; use a Pacing Board or an Alphabet Board if necessary • use Intelligibility Drills in which the client reads aloud printed words; judge the accuracy solely on the basis of phonatory cues and give corrective feedback or positive reinforcement • teach correct articulation by Phonetic Placement Method which shows correct placement of articulators for producing target sounds • improve speech intelligibility by asking the client to produce word-medial and final consonants with a certain degree of exaggeration • use the Minimal Contrast Method in which the client is taught to produce clearly pairs of words that differ by only one phoneme (e.g., pat-bat) ● Modify prosodic problems • note that a slower rate can improve the client’s prosody • teach proper intonation through printed sentences that show rising and falling pitch by arrows • use Contrastive Stress Drills • teach appropriate chunking of words according to syntactic units (e.g., pausing at the end of a grammatic clause and a sentence) Duffy, J.

Mixed Dysarthria. A type of motor speech disorder that is a combination of two or more pure dysarthrias; the neuropathology is varied depending on the types of dysarthrias that are mixed; frequent causes include multiple strokes or multiple neurological diseases; speech disorders are varied and dependent on the types of pure dysarthrias that are mixed; select appropriate treatment targets and procedures described under Treatment of Dysarthria; in addition, consider the following that apply especially to mixed dysarthrias: ● Make a thorough assessment of the client’s symptom complex of mixed dysarthria; consult the cited sources and the PGASLP ● Identify the dominant type, if any, and describe the major speech problems ● Select speech targets that when treated will immediately improve communication ● Treat those targets like you would in the case of pure dysarthrias ● Note that some clinicians recommend that problems of respiration, resonation, phonation, articulation, and prosody, if all present, be treated in that order ● Treat the most severe problem first if multiple problems exist in a single category (e.g., prosody); find out the client’s preference to determine which problems should be addressed first in treatment ● Recommend Augmentative Communication devices for clients who need them; note that clients whose 212

Spastic Dysarthria. A type of motor speech disorder caused by bilateral damage to the upper motor neuron (direct and indirect motor pathways) resulting in weakness, spastic paralysis, limited range of movement, and slowness of movement; may affect all aspects of speech; major speech problems include imprecisely produced consonants, monopitch, monoloudness, reduced stress, hypernasality, slow rate, strainedstrangled-harsh voice, pitch breaks, and breathy voice; select appropriate treatment targets and procedures described under Treatment of Dysarthria; in addition, consider the following that apply especially to spastic dysarthria: ● Make a thorough assessment of dysarthria and the total symptom complex; make a differential diagnosis of spastic dysarthria; consult the cited sources and PGASLP ● Consult with the client’s physician about medically controlling pathological crying, which might interfere with treatment ● Consider behaviorally modifying crying in treatment sessions by reinforcing noncrying (alternative) behaviors 213

Dysarthria: Spastic ● Do not teach pushing or pulling exercises that only
aggravate hyperadduction
D
● Use relaxation and stretching exercises with caution
because their effects on speech have not been documented ● Note that modification of respiratory behaviors is typically not a major concern in clients with spastic dysarthria; any apparent respiratory problems may be due largely to such phonatory problems as hyperadduction of vocal folds ● Modify phonatory problems • note that efforts to reduce hyperadduction of vocal folds have not been especially successful; nonetheless, these efforts may be made with caution • teach the client head and neck relaxation by instruction, modeling, and manual guidance; stand behind the client, take the client’s head between the two hands, and gently tilt it back, move it forward, and to the sides; ask the client to move the head in the same manner without manual guidance • teach easy onset of phonation to a client who has learned to relax the neck and head muscles; model soft glottal closure and ask the client to imitate it; begin with an exhaled sigh and add a prolonged /a/; shape this relaxed production of /a/ into words, phrases, sentences, and spontaneous speech • teach the yawn-sigh motion before starting a gentle phonation; ask the client to inhale through open mouth, exhale, and begin phonation; shape the phonated speech into words, phrases, sentences, and spontaneous speech ● Modify resonance problems • increase vocal loudness to control the extent of hypernasality, as louder speech tends to be perceived less nasal
214
Dysarthria: Spastic • discuss the usefulness of Pharyngeal Flap Operation with the client’s physician or a Palatal Lift Prosthesis with a prosthodontist ● Modify articulatory problems • note that the effects of tongue and lip stretching exercises that some clinicians recommend have not been documented in controlled studies • use discretion in using such stretching exercises as gently pulling a client’s lip or tongue out by holding it with a gauze pad; if used, carefully document the effects of such procedures and abandon them if data are negative • note that traditional articulation treatment may be more effective than stretching exercises; use Intelligibility Drills in which the client reads a list of words and the clinician judges the accuracy of production solely on the basis of phonetic cues and gives appropriate feedback on correct and incorrect productions • use Phonetic Placement Method to teach correct placement of articulators; show articulatory placements in a mirror if necessary; model and reinforce imitated and eventually evoked productions of target words, phrases, and sentences • teach the client to produce the medial and final consonants in words in an exaggerated manner • use Minimal Contrast Drills in which pairs of words that differ by only one phoneme are used to teach correct productions of target sounds ● Modify prosodic problems • ask the client to vary pitch on a prolonged vowel production (e.g., /a/); if necessary, model pitch variations as you prolong the target vowel; reinforce correct imitations; fade modeling and ask the client to vary his or her pitch

Unilateral Upper Motor Neuron Dysarthria. A type of motor speech disorder caused by damage to the upper motor neurons that supply cranial and spinal nerves involved in speech production; primarily a disorder of articulation in which the dominant speech problem is imprecise production of consonants; less significant speech symptoms include harsh voice quality, slow, imprecise, or irregular Alternating Motion Rates; gen216

Dysfluencies. Behaviors that interrupt fluency; measured in diagnosing Stuttering; specific forms include repetitions of sounds, syllables, words, and phrases; prolongations of sounds and articulatory postures; inter- and intralexical pauses; interjections of syllables, words, and phrases; revisions; and incomplete phrases; see PGASLP for examples and assessment procedures.
Dysphagia. Disorders of swallowing, also known as disorders of deglutition; associated with many medical conditions including neuromuscular disorders and cancer of the larynx and the surgical removal of structures involved in swallowing; may occur at any age although more common in the elderly. Disorders of Mastication. Problems in chewing food; may be due to reduced range of movement by the tongue and the mandible, reduced buccal tension, and poor alignment of mandible and maxilla.
Disorders of the Preparatory Phase of the Swallow. Problems in collecting the masticated food to form a bolus as a preparation for swallow; may be due to problems in labial closure, tongue movement and coordination, appropriate holding of the bolus in the mouth (e.g., holding it in the front of the mouth), and reduced oral sensitivity. Disorders of the Oral Phase of the Swallow. Problems in the tongue movement to initiate the voluntary aspect of the swallow and in passing the food over the base of the tongue; by the end of the phase, the bolus will
218
Dysphagia: Treatment have reached the faucial arch area; problems due to tongue thrust, reduced tongue tension and movement, and reduced buccal tension.
Disorders of the Pharyngeal Stage of the Swallow. Problems in propelling the bolus through the pharynx and into the P-E segment; may be due to delayed or absent swallowing reflex, inadequate velopharyngeal closure, reduced pharyngeal Peristalsis, pharyngeal paralysis, laryngeal movement disorders, and so forth.
Disorders of the Esophageal Phase of the Swallow. Problems in passing the bolus through the cricopharyngeus muscle and past the 7th cervical vertebra; due to many muscular and other problems including weak cricopharyngeus, esophageal Peristalsis, and esophageal obstruction (e.g., by a tumor). Treatment of Dysphagia. Management of swallowing problems by a variety of medical and nonmedical procedures; speech-language pathologists may implement most of the nonmedical procedures. General Guidelines ● Make a thorough assessment and diagnosis of the swallowing disorders of the client; consult the cited sources and the PGASLP ● Consider the following factors in deciding whether to treat and with what procedures: • diagnosis of the swallowing disorder and related medical condition of the client; if the disorder is likely to be cleared within a week or two, do not initiate an exercise program; teach a few compensatory strategies; if the patient has significant motor neuron disease, do not initiate range-of-motion exercises that may only tire the client; if the patient cannot follow directions because of dementia, do not select procedures that require the client to comprehend instructions

• prognosis for swallowing therapy is good for patients who have had strokes, traumatic brain injury, gun shot wounds, radiation therapy for neck and head cancer; hence, swallowing therapy is recommended; prognosis is not favorable for patients whose degenerative neurological disease has advanced to a stage where therapy is ineffective • success in food intake with compensatory strategies suggests that an exercise program may not be needed • very severe dysphagia exhibited during assessment suggests that the patient needs indirect therapy; exercises to increase muscle movements and their range in the absence of food in the mouth may be necessary • poor respiratory function indicates a need to postpone certain therapy procedures until this function is improved • caregiver support to help complete prescribed exercises at home; caregivers should be available and willing to remind the client to perform the exercises and supervise them when necessary • patient’s motivation and interest, without which no treatment program will work Discuss with the client and the family the swallowing process and the treatment procedure to be implemented Give written instructions to the patient and describe the steps to be followed Ask the patient to first practice swallow (without solid or liquid food) Note that patients are likely to reject or eat only a small amount of a variety of food if its bolus takes more than 10 seconds for pharyngeal and oral transit; such patients need to use at least a supplemental nonoral feeding program to sustain themselves 220
Dysphagia: Compensatory Treatment ● Note that patients who aspirate 10% of each bolus
and are aware of it will reject food that causes it
● Introduce only a small amount of food during direct
treatment
● Show the client the amount of be swallowed ● Instruct the patient to cough to clear the airway and
reinforce the client’s coughs
● Initiate indirect treatment if the patient aspirates
10% of each bolus and the direct methods do not progressively reduce aspirations (intake of food into lungs); be aware that only radiographic data show aspiration ● Concentrate on increasing muscle control during indirect treatment ● Reduce distraction during treatment Compensatory Treatment. Procedures that promote swallowing without modifying the physiological status of the patient; mostly clinician- or caregiver-managed; requires little or no patient effort and thus does not tire the patient; includes a variety of procedures. ● Modification of patient’s posture: Use postural modification until swallowing improves or direct treatment may be initiated; instruct the patient to assume a posture that promotes better swallow and reduces or eliminates aspiration • the chin-down posture that widens the vallecullae; teach the client to tuck the chin to the chest during swallow while maintaining a straight cervical spine; recommended for patients with delayed triggering of the pharyngeal swallow; may be effective with patients who have reduced posterior motion of the tongue base; patients with inadequate laryngeal elevation, poor vocal fold closure, and absent cough reflex may not benefit from chin tuck • the chin-up posture that helps drain food from the oral cavity because of gravity; teach the patient to 221

Dysphagia: Compensatory Treatment
D
tilt the head back by extending the neck by leaning the head back; most effective with patients in whom the oral transit of the bolus to the pharynx is difficult; not recommended for patients with neurogenic dysphagia • head rotation toward the weaker side that helps direct food to a more efficient side of the pharynx; teach the patient to rotate the head during swallow toward the damaged, weaker, or hemiparetic side of the pharynx, which then gets narrowed; recommended for patients with unilateral laryngeal dysfunction resulting in aspiration • combined chin-down and head rotation may reduce aspiration in some patients with inadequate laryngeal closure; teach this if a trial application supports this combination • head tilt to the stronger side, which directs food to that side; teach this strategy to patients with unilateral oral and pharyngeal weakness; the patient may need consistent cues to do this • lying down on one side, which helps control diffuse residue in the pharynx; teach this to patients in whom pharyngeal wall constrictions are bilaterally reduced, causing aspiration after the swallow; after eating lying down and before sitting up, teach the client to cough to clear the traces of food in the pharynx ● Increased oral sensory awareness: Procedures that enhance oral sensory awareness prior to swallow may be beneficial and include a variety of procedures; recommended for patients with swallow apraxia, delayed onset of the oral swallow, reduced oral sensation, delayed triggering of the pharyngeal swallow, and tactile agnosia for food; in all the techniques, a sensory stimulus is applied before an attempted swallow; presumably, the stimulus alerts the swal222
Dysphagia: Compensatory Treatment lowing centers of the brain; use one or more of the following sensory enhancement techniques • apply a downward pressure on the tongue while presenting food with a spoon • present a sour bolus (50% lemon juice, 50% barium) before presenting the bolus • present a cold bolus • present a bolus that the patient needs to chew • present a bolus of larger volume • present a thermal-tactile stimulation before presenting a bolus; using a size 00 laryngeal mirror that has been dipped in crushed ice for several seconds, firmly rub the anterior faucial arch four or five times before presenting a bolus; this is expected to sensitize the system so that initiation of oral swallow will trigger pharyngeal swallow; note, however, there is controversy about its effectiveness ● Modification of volume and speed of food presentation: Procedures that change the amount of food presented and the rate of presentation that facilitate swallowing; use the following techniques • Try a larger bolus to trigger pharyngeal swallow in patients • Try a smaller bolus to trigger swallowing in some patients • Present smaller boluses at a slower rate to trigger swallowing in some patients ● Modification of food consistency: Procedures in which the food consistency or viscosity is changed to promote better swallow; try the following modifications • use thin liquids with patients who have oral tongue dysfunction, reduced tongue base retraction, reduced pharyngeal wall contraction, reduced laryngeal elevation, and reduced cricopharyngeal opening 223
D
Dysphagia: Swallow Maneuvers
D
• use thickened liquids with patients who have oral tongue dysfunction and delayed pharyngeal swallow • use purees and thick foods (including thickened liquids) with patients who have delayed pharyngeal swallow, reduced laryngeal closure at the entrance, and reduced laryngeal closure throughout • eliminate a certain food consistency only as a last resort ● Use of intraoral prostheses: Artificially fashioned devices that help compensate physiologic deficiencies; have them constructed with the help of a maxillofacial prosthodontist • use a palatal lift prosthesis, which helps lift a paralyzed soft palate to close the velopharyngeal port • use a palatal obturator, which closes a surgically resected soft palate in patients who have had oral cancer • use a palatal augmentation or reshaping prosthesis, which gives a new and more normal shape to the hard palate in patients who have had oral surgery Swallow Maneuvers. Techniques designed to help patients gain voluntary control over certain involuntary aspects of swallow; to be effective, the patient should follow the directions and exert some muscular force, which may be impractical in some cases; use one of the four most commonly used maneuvers. ● the supraglottic swallow, which helps close the airway at the level of vocal folds before and during the swallow; it involves holding the breath during swallow to close the vocal folds: to implement this maneuver, place a bolus in the mouth of the patient and ask the patient to: • hold the food in the mouth • take a deep breath and hold the breath 224
Dysphagia: Swallow Maneuvers • swallow while holding the breath • cough soon after the swallow Note that some patients may hold the breath by not closing the vocal folds, but by stopping the chest wall movement. Ask these patients to inhale deeply, exhale slightly, and then hold the breath and swallow while holding the breath; holding the breath on exhalation closes the folds more readily. ● the super-supraglottic swallow, which helps close the airway entrance before and during the swallow; it helps close the false vocal folds by tilting the arytenoid cartilage anteriorly to the base of the epiglottis before and during the swallow; arytenoids are tilted when the breath is held and the patient bears down; to implement this maneuver, ask the patient to: • inhale and hold the breath tightly by bearing down • swallow while holding the breath and bearing down ● the effortful swallow, which helps increase the posterior motion of the tongue base during the pharyngeal swallow; to implement this maneuver ask the patient to: • squeeze as hard as possible while swallowing ● the Mendelsohn maneuver, which helps elevate the larynx more and for longer duration, resulting in an increased width and duration of the cricopharyngeal opening; in implementing this maneuver: • educate the patient about the elevation of the larynx (tell them about the Adam’s apple or voice box going up) • have the patient palpate the elevation of the larynx when he or she swallows saliva several times • instruct the patient to hold the larynx up for a longer duration (several seconds) as he or she swallows; give such instructions as ‘‘swallow long and strong’’ or ‘‘stretch out the swallow’’ 225

Dysphagia: Direct Treatment
D
Direct Treatment of Dysphagia. Treating swallowing disorders by placing food or liquid in the patient’s mouth and then shaping and reinforcing swallowing behaviors. Disorders of Mastication ● Instruct the patient with limited lateral tongue movement to mash food by pressing the tongue against the hard palate or by keeping the food on the more mobile side of the tongue ● Teach the patient with reduced buccal tension to: • apply a gentle pressure with one hand on the damaged cheek to increase cheek tension • put food on the normal or stronger side • keep the head tilted to the stronger side to maintain food on that side ● Teach the patient with limited lateral movement of the mandible to mash food by pressing the tongue against the palate ● Design a Palate Reshaping Prosthesis for the patient with limited vertical tongue movement when indirect treatment (exercises) fail ● Gradually reshape the prosthesis by reducing its size as the patient’s vertical tongue movements improve Disorders of the Preparatory Phase of the Swallow ● Teach the patient with problems in forming and holding the bolus due to reduced tongue movement and coordination to • tilt the head forward to keep the food in front of the mouth until ready to swallow • tilt the head back to promote the swallow • consciously hold the bolus in the anterior or middle portion of the mouth ● Teach the patient with reduced oral sensitivity to • place food on the side of the oral cavity with better sensitivity 226
Dysphagia: Direct Treatment • better appreciate the placement of food by placing cold or spicy food in the mouth Disorders of the Oral Phase of the Swallow ● Teach the patient who has developed a tongue thrust to: • place the tongue on the alveolar ridge and initiate a swallow with an upward and backward motion • compensate by placing food at the back of the tongue and then to initiate a swallow ● Teach the patient with reduced tongue elevation to: • compensate by placing food posteriorly in the oral cavity • place the straw almost at the level of the faucial arches to help swallow liquid • tilt the head back and let gravity push the food from the oral cavity into the pharynx • use the Supraglottic Swallow Maneuver to voluntarily protect the airway, if aspiration is a concern ● Teach the patient with disorganized anterior to posterior tongue movement to • hold the Bolus against the palate with the tongue • begin the swallow with a strong, single posterior motion of the tongue ● Teach the patient with a scarred tongue to: • place food behind the scarring • tilt the head posteriorly to allow gravity to help with oral transit Disorders of the Pharyngeal Stage of the Swallow ● Teach the patient with delayed or absent swallowing reflex to compensate by: • tilting the head forward while swallowing • limiting the amount of Bolus that does not overflow into the open airway • counsel the family about the delay in initiating the swallow reflex; ask them to allow that much extra time for each swallow 227

pensatory behaviors as: • switching between liquid and semisolid swallows so that the liquid swallows help clear the pharynx • taking only liquids or semisolids • initiating dry swallows after each swallow of food to clear the pharynx • the Supraglottic Swallow Maneuver Teach the patient with unilateral pharyngeal paralysis such compensatory behaviors as: • turning the head toward the affected side to close the pyriform sinus on the affected side and to direct the food down the normal side • tilting the head toward the stronger side if the patient has a unilateral paralysis in lingual function and the pharynx • the Supraglottic Swallow Maneuver • washing away residual thicker food with liquid swallows Ask patients with cervical osteophyte to limit their diet to semisolid or liquid food until surgery corrects the problem and the patient recovers Teach the patient with a scarred pharyngeal wall the same compensatory behaviors used for the patient with unilateral pharyngeal paralysis Teach the patient with reduced laryngeal elevation to clear the throat after each swallow Use the Supraglottic Swallow Maneuver if residual material needs to be removed from the pharynx Teach the patient with reduced laryngeal closure to: • use the Supraglottic Swallow Maneuver • tilt the head forward while swallowing • turn the head to the side that is not functioning properly • place pressure on the thyroid cartilage on the damaged side to improve closure 228
Dysphagia: Indirect Treatment Disorders of the Esophageal Phase of the Swallow ● Do not attempt to treat, as these are handled medically Indirect Treatment for Dysphagia. Treatment of swallowing problems using exercises designed to improve the muscle functioning; does not involve food. Oral-Motor Control Exercises ● Treat the patient with reduced range of tongue movements with such exercises as the following; ask the patient to: • open the mouth as wide as possible and raise the tongue in front as high as possible; hold the tongue for 1 second, and then lower it • raise the posterior part of the tongue as far as possible; hold it for 1 second, and then lower it • continue with the stretching exercises for 5–10 times in a session, for 3–4 minutes • repeat the set of exercises 5–10 times per day ● Increase the patient’s buccal tension by asking the patient to: • stretch the lips as tightly as possible and say ‘‘e’’ • round the lips tightly and say ‘‘o’’ • rapidly alternate between ‘‘e’’ and ‘‘o’’ ● Instruct the patient with limited lateral movement of the mandible to: • keep the jaw open as widely as possible and hold this position for about 1 second • open and move the jaw sideways and hold the extended position for 1 second • make circular jaw movements • provide Manual Guidance to move the jaw in the desired directions • stop the task if any pain is experienced ● Treat the patient with limited tongue resistance by asking the patient to: • push the tongue against a tongue depressor and hold the pressure for 1 second 229
D
Dysphagia: Indirect Treatment
D
• push the tongue against the tongue blade, in an upward, forward, and sideways direction; hold the pressure for 1 second ● Shape more firm lip closure by asking the patient with problems in lip closure to: • stretch the lips for 1 second to stimulate the production /i/; increase the duration gradually • pucker the lips tightly for 1 second initially; increase duration gradually • close the lips tightly for 1 second; increase the duration gradually; provide Manual Guidance if necessary • close the lips around a spoon or an object; reduce the size of the object as the patient’s lip closure improves • to hold the lips together for 1 minute once a lip seal is achieved; increase the duration gradually • repeat the exercises 10 times per day • ask the patient to close the lips around a tongue depressor • maintain lip closure when you or the patient tries to open them ● Treat the patient with bolus control problems by asking the person to grossly manipulate materials by: • holding a flexible licorice whip in the mouth, with one end on the patient’s tongue and the other end in the clinician’s hand • keeping the licorice stick between the palate and the tongue • moving the licorice stick from side to side with the tongue • moving the licorice stick forward and backward with the tongue, and then report where the licorice stick is • reporting when gross movement of the licorice stick is achieved
230
Dysphagia: Indirect Treatment • moving the licorice stick in a circular motion starting from the center of the mouth • chewing a piece of gum as manipulation capabilities improve ● Treat the patient with bolus control problems who has learned to grossly manipulate materials by: • placing a small bolus of paste consistency on the tongue • asking the patient to move the bolus around in the mouth • telling the patient not to spread the bolus around in the mouth • asking the patient not to lose the bolus • instructing the patient to cup the tongue around the bolus • expectorating the bolus once the task is complete (inspect the mouth for residue) • varying the consistency of the bolus, once success is achieved • introducing one-third of a teaspoon of liquid to the patient’s mouth once success is achieved with the paste ● Treat the patient with bolus propulsion problems through posterior bolus propulsion exercises • place a long wad of gauze that is dipped in fruit juice in the patient’s mouth • hold one end of the gauze • ask the patient to use the tongue to push the gauze up and back Stimulating the Swallow Reflex ● Hold a small, long-handled laryngeal mirror in ice water for about 10 seconds ● Place the laryngeal mirror at the base of the anterior faucial arch ● Repeat this light contact 5–10 times

Dysphagia: Indirect Treatment ● Observe the likely rise of the thyroid cartilage, the
D
twitching of the soft palate, and a slight movement of the faucial arches ● Ask the patient to swallow after the stimulation without food ● After repeating light contact stimulation some 5–10 times, release a small amount of liquid into the patient’s mouth with a pipette and ask the patient to swallow by saying ‘‘Now’’ ● Repeat stimulation exercises four to five times daily for 3 weeks to a month in the case of patients with severely impaired swallow reflex ● Shape swallowing once the reflex begins to trigger by progressively larger amounts of food and food with greater consistency Improving Adduction of Tissues at the Top of the Airway ● Teach lifting and pushing exercises to improve laryngeal adduction to protect the airway during swallowing; ask the patient to: • sit on a chair and hold his or her breath as tightly as possible • use both hands and push down, or pull up on the chair, while holding the breath for 5 seconds • use only one hand while pushing down or pulling up on the chair and to try and produce clear voice with each trial; repeat this exercise five times • use Hard Glottal Attack and repeat ‘‘ah’’ five times • repeat the exercises three times in succession, 5–10 times a day for 1 week • lift or push with simultaneous voicing; use both hands, pull on a chair, and use prolonged phonation • use Hard Glottal Attack, commence phonation on ‘‘ah,’’ and sustain phonation with smooth voice quality for 5–10 seconds
232
Dysphagia: Medical Treatment • practice a Pseudo Supraglottic Swallow; instruct the patient to inhale, hold the breath, and use a strong cough Medical Treatment of Dysphagia. Use of medical, mostly surgical, procedures to treat dysphagia; these procedures are designed to (a) improve a specific anatomic or physiologic deficiency related to swallow, (b) eliminate or reduce aspiration, and (c) provide food and liquid nonorally; medications are limited to treating esophageal swallowing disorders, not for improving oral or pharyngeal swallowing problems. Botulinum Toxin Injection. A surgical procedure of injecting botulinum, a toxic substance, into cricopharyngeal muscle to improve swallowing; technically difficult because of the position of the target muscle (hidden behind the cricoid cartilage); misplaced botulinum can paralyze other muscles resulting in more serious dysphagia. Cricopharyngeal Myotomy. A surgical procedure of splitting the cricopharyngeal muscle from top to bottom to keep a permanently open sphincter for swallowing; fibers of the inferior constrictor above and the esophageal musculature below also may be slit; eating may be resumed within about a week; recommended for patients with Parkinson’s disease, amyotrophic lateral sclerosis, and oculopharyngeal dystrophy whose main problem is cricopharyngeal dysfunction; not to be performed in early phases of recovery from stroke, head injury, or spinal cord injury as these patients are likely to recover normal or near normal swallow. Epiglottic Pull-Down. A surgical procedure designed to control unremitting aspiration; the epiglottis is sutured to the arytenoids by making incisions around the epiglottis, aryepiglottic folds, arytenoids,
233

and interarytenoid area; the procedure may fail in some cases, as the epiglottis tends to pull away from this attachment. Esophagostomy. A nonoral, surgical feeding method for dysphagic patients who cannot tolerate oral feeding; insertion of a feeding tube into the esophagus and stomach through a hole (stoma) surgically created through cervical esophagus. Gastrostomy (G-Tube). A nonoral, surgical feeding method for dysphagic patients who cannot tolerate oral feeding; insertion of a feeding tube into the stomach through an opening in the abdomen; may be inserted under general anesthetic (called operative gastrostomy) or precutaneously with local anesthetic with the help of an endoscope (called precutaneous endoscopic gastrostomy); blended table food is directly transported to the stomach; recommended when long-term (more than 30 days) nonoral feeding is required; may be more or less permanent; can be removed when no longer needed. Jejunostomy. A nonoral, surgical feeding method for dysphagic patients who cannot tolerate oral feeding; insertion of a feeding tube into the jejunum through the abdominal wall; jejunum is that portion of the small intestine that extends from duodenum to the ileum; often recommended to reduce reflux; the food needs to be prepared because it enters the body below the stomach. Laryngeal Bypass or Tracheoesophageal Diversion. A surgical procedure designed to separate the air and food passages to prevent or reduce aspiration; recommended for severely neurologically involved patients with life-threatening aspiration; the trachea is cut at the third or fourth tracheal ring; the proxi-
234
Dysphagia: Medical Treatment mal end is sutured into the cervical esophagus, and the distal end is bent forward to bring it up to the skin where an opening is made and sutured to it; prevents phonation; a tracheoesophageal stunt voice prosthesis will help develop esophageal speech. Laryngeal Closures. A surgical procedure to minimize or eliminate unremitting aspiration; in one procedure, the vocal folds are sutured together to prevent aspiration; in the other procedure, false vocal folds are sutured together. Laryngeal Suspension. A surgical procedure to promote laryngeal elevation in patients whose larynx does not raise up and move forward to help close the airway during swallow; the procedure raises the larynx and tilts it forward under the base of the tongue; a suture made from the middle of the mandible to the laryngeal cartilage helps accomplish this; head and neck cancer patients, not neurological patients, are candidates for this procedure. Medialization Laryngoplasty (Thyroplasty). A surgical method now preferred to Teflon injection to the vocal folds; designed to help position a paralyzed vocal fold into a more medial position so the folds can approximate for phonation and swallowing without aspiration; a small silicon prosthesis is placed in a window surgically created in the thyroid cartilage at the level of the paralyzed fold; the prosthesis helps position the paralyzed fold in a more medial position; performed under local anesthesia; has been successful in achieving complete medialization of a paralyzed fold. Medications. Medications are available for patients whose swallowing disorders are due to such neurological diseases as Parkinson’s disease, myasthenia gravis, and multiple sclerosis; these patients

have esophageal swallowing disorders; note that patients with oral-pharyngeal swallowing problems typically are not treated with medications. Nasogastric Feeding (NG Tube). A nonoral feeding method for dysphagic patients who cannot tolerate oral feeding; a tube inserted through the nose, pharynx, and esophagus into the stomach feeds the patient; recommended when this type of feeding is needed for a short duration (less than 30 days); less acceptable to patients than some of the other procedures because of constant nasal irritation and social appearance. Pharyngostomy. A nonoral, surgical feeding method for dysphagic patients who cannot tolerate oral feeding; insertion of a feeding tube into the esophagus and stomach through a hole (stoma) surgically created through the pharynx; often more acceptable to patients than the nasogastric feeding. Surgical Reduction of Cervical Osteophytes. A surgical procedure to remove the bony growth on the cervical vertebra that can narrow the pharyngeal area, displace the posterior pharyngeal wall anteriorly, and thus cause swallowing problems; the procedure poses risk of nerve damage and causing a more serious dysphagia. Teflon Injection Into the Vocal Folds. A surgical implant method to improve airway closure during swallowing in dysphagic patients by adding implanted muscle mass that will help close the airway; Teflon may be injected into a normal or reconstructed vocal fold or any remaining tissue on top of the airway; other substances injected include glycerin and gel foam; often performed on patients who undergo partial laryngectomy; also performed on patients with such neurological disorders as Parkinson’s disease; note that aspiration caused by 236
Dysphonia lack of vocal fold closure may occur only in 10% of patients; its use is on the decline because of such complications as the formation of Teflon granuloma. Total Laryngectomy. Total removal of the hyoid bone and the larynx to permanently separate the food and air passages; performed on patients who already have undergone partial laryngectomy and now cannot control aspiration; a last-resort procedure to control aspiration. Tracheostomy. A surgical procedure to reduce or eliminate aspiration and improve pulmonary toilet; partially protects the lower respiratory tract from material that may pass the laryngeal sphincter; however, the procedure’s effectiveness in reducing aspiration is limited.

Teaching a client to auditorily discriminate between speech sounds as against teaching production of those sounds; the same as Auditory Discrimination Training or Perceptual Training; see also, Traditional Approach under Treatment of Articulation and Phonological Disorders: Specific Techniques or Programs.
Effectiveness of Treatment. Assurance that treatment, not some other factor, was responsible for the positive changes documented in a client under treatment; requires controlled evidence gathered through clinical experimentation; data should show that treatment was better than no treatment; may use a group experimental design or a single-subject experimental design to establish this; not the same as Improvement or Functional Outcomes.
Effortful Closure Techniques. Behavioral treatment techniques to promote laryngeal adduction for clients with unilateral or bilateral vocal fold paralysis or weakness as found in many clients with dysarthria; the client is taught to grunt, cough, push, lift, and pull while trying to phonate; the muscular effort helps push the folds together.
Effortful Swallow. A swallowing maneuver that helps increase the posterior motion of the tongue base during the pharyngeal swallow; to implement this maneuver, ask the patient to: ● Squeeze hard with all of the muscles as he or she swallows
Electronic Communication Systems. Methods of augmentative communication for persons with limited or no oral speech; also known as electronic gestural-assisted communication strategies, these systems use electronic devices with a switching mechanism to activate a message and control the electronic system and use a display that shows the 240

Electronic Device for Alaryngeal Speech (Electrolarynx). Hand-held electronic instruments that generate sound; used by persons who have undergone laryngectomy to produce alaryngeal speech; for rehabilitation procedures, see Laryngectomy; Treatment Procedures: Laryngectomy.
Electronic Gestural-Assisted Communication Strategies. The same as Electronic Communication Systems. Elicited Aggression. Aggressive behavior directed against any object or person when an aversive stimulus (as in operant punishment procedures) is delivered; not necessarily directed against the person delivering the aversive stimulus; a potential undesirable side-effect of punishment. ● A child may kick the table when ‘‘No’’ is said to a wrong response ● A child may sweep the stimulus materials off the table when a token is taken away in a response cost procedure ● Note that to reduce elicited aggression in treatment, use punishment procedures sparingly and use more positive reinforcement and discriminative reinforcement that may indirectly control undesirable behaviors Hegde, M. N. (1998). Treatment procedures in communicative disorders (3rd ed.). Austin, TX: Pro-Ed.
Empirical Validity. Credibility or truthfulness of statements based on research data; assurance that treatment procedures have been shown to be effective through experimentation involving clients (as against logical arguments or scholarly speculation); a criterion for treatment selection.

between antecedents, responses, and the consequences the responses generate and thus help maintain those responses; environmental events that shape and sustain behaviors; reinforcers and punishers used in treatment in a manner that immediately follow the target behaviors; the treatment variable in behavioral approach; contrasted with Genetic/ Neurophysiological Contingency with which it interacts. Escape. A behavior that reduces or terminates an aversive event and hence increases in frequency; typically leads to avoidance; often maladaptive as in a stutterer’s avoidance of speaking situations; reduction of avoidance may be a clinical goal. ● Work on eliminating the aversiveness of the event by teaching the needed, alternative skill (e.g., increased fluency in difficult speaking situations) ● In gradual steps, encourage the client to come in contact with the aversive event (avoided speaking situation) ● Reinforce the approach behavior (e.g., picking up the telephone instead of having someone else respond) Escape Extinction. A procedure to reduce negatively reinforced behaviors by blocking an escape and thus preventing negative reinforcement for it; a response reduction strategy; useful in treatment sessions in which children exhibit many undesirable behaviors to escape from treatment regimen (e.g., crawling under the table during treatment). ● Prevent the occurrence of an undesirable response (e.g., crawling under the table) exhibited to escape from aversiveness (e.g., training trials) ● Physically restrain the child every time an attempt is made to leave the chair to prevent reinforcement of escape behavior ● Measure the frequency of attempts to crawl; if there is no reduction, use a different technique Ethnocultural Variables in Treatment. Variables related to an individual’s cultural, ethnic, and other personal 242
Ethnocultural Variables in Treatment variables that may affect treatment of communicative disorders; there is more written about assessment of ethnoculturally varied clients’ disorders of communication; research on the effects of ethnocultural variables on treatment techniques is limited; see under each disorder entry (e.g., Aphasia, Articulation and Phonological Disorders, Language Disorders in Children) for specific and detailed guidelines on treating clients with varied ethnocultural backgrounds; a few major and general guidelines include the following: ● Select assessment procedures that are ethnoculturally relevant; see PGASLP for guidelines ● Note that many of these suggestions are relevant to any disadvantaged family, not just a minority family; many poor, less educated, rural, and working-class families of any race may face problems similar to those faced by families of ethnocultural minority communities ● Understand the cultural communication patterns of the client and the family ● Understand the families’ views and beliefs about health, wellness, illness, specific diseases, disability, handicap, and impairment ● Find out the family members’ beliefs about disorders of communication and the value they place on communicative skills ● Find out about the educational levels and sophistication about health care systems; without imposing a clinical recommendation, educate the client and the family about clinical resources available to them ● Understand the family environment, living conditions, financial resources to support treatment that needs to be paid for; help them find financial support from local, regional, state, federal, and private sources to help pay for clinical services ● Find out about a family’s transportation needs; many do not receive help in speech and hearing clinics because they cannot afford to travel to clinical facilities that often are 243

located in distant areas from where disadvantaged people live Assess the time that is available for family members to get involved in clinical treatment, home treatment, and communication skill maintenance over time Understand the phonological, semantic, syntactic, and pragmatic rules of the client’s dialect (e.g., African American English or an English dialect influenced by a primary language in a bilingual child) Place communication patterns in the larger cultural context; avoid the narrow view of differences in linguistic rules among the languages of different ethnic groups Achieve a larger understanding of culture, literature, history, and heritage of the people served; avoid the pitfalls of stereotypic and narrow linguistic descriptions of differences; note that this is an enriching experience to clinicians themselves Do not assume that clients of different ethnocultural background automatically reject the mainstream communication patterns or that they have not acculturated to mainstream values—many have; the only right thing to do is to find out in an objective and nonevaluative manner Do not accept cultural stereotypes about any group; for instance, do not assume that a boy from an Asian background does not maintain eye contact during conversation with his teacher because of his cultural background; he may have learned to avoid eye contact because of his stuttering Work with your colleagues to make sure that needed interdisciplinary services are made available to the clients and their families Receive family input in selecting treatment targets; recommend the targets you think are appropriate for the client, but discuss them with the client and his or her family members; make modifications in light of this discussion Serve as a resource to other professionals in helping them understand communication patterns of ethnoculturally 244

different clients and their families so that communication between service providers and receivers is more effective Treat communicative disorders that are diagnosed with ethnoculturally appropriate assessment; for instance, treat articulation disorders in African American children only when they have a disorder in African American English; in bilingual children, treat articulation disorders only if they have a disorder within the phonological system of their primary language or a disorder in English that is not due to the primary language’s phonological patterns; treat a dialectal variation to induce standard English patterns only when the client, family, or both demand it Select treatment stimulus materials that are ethnoculturally appropriate; select materials that the clients are familiar with; in the case of children, find out their preferences in selecting toys, pictures, line drawings, objects, and other stimulus materials; seek family members’ input and, if possible, select treatment stimuli from the client’s home environment (e.g., ask the child to bring his or her favorite toys to treatment sessions and use them as stimuli for treatment tasks) Select treatment procedures that are known to have ethnocultural generality; evaluate treatment studies for their subject selection criteria; apply a given treatment procedure with caution if, in experimentally testing that procedure, an ethnoculturally diverse population has not been adequately sampled Select participants from varied ethnocultural backgrounds for your clinical treatment research In the absence of treatment research data on a particular disorder in a particular ethnic group (which is typically the case), assume tentatively that generally effective treatment procedures might work with clients of varied ethnocultural background; note that such treatment principles as modeling, demonstration, instructions, positive reinforcement, corrective feedback, extinction, differential 245

reinforcement, shaping, and so forth have been researched with good generality; nonetheless, expect to modify them to suit individual clients ● Gather systematic client performance data on treatment procedures that are of unknown ethnocultural generality; if possible, publish your data as case studies to help other clinicians select treatment procedures appropriate for their varied clients ● Modify treatment procedures in light of the performance data and the client’s ethnocultural background; publish information and data on such modifications that were found to be effective with certain clients Kayser, H.

Event Structures. Sequentially organized, familiar events taken from daily life and routinized to teach language structures to children; for procedures, see Language Disorders in Children; Treatment of Language Disorders: Specific Techniques or Programs.
Evoked Trials. Structured opportunities to produce a response when the clinician does not model; part of the discrete trial procedure; often used in the beginning stages of treatment; most useful in teaching articulation and language structures; contrasted with Modeled Trials; include Baseline Evoked Trials and Treatment Evoked Trials; in administering an evoked trial: ● Present a stimulus, such as a picture or an object, to the client by placing it on the table 246
Exemplar ● Ask a relevant question (e.g., ‘‘What is this?’’ ‘‘What do
you see?’’ ‘‘What are these?’’ and so forth)
● Allow a few seconds for the client to respond ● Move the picture or object toward you ● Record the response as correct or incorrect; if no response,
record this fact as well ● Represent the stimulus and begin another trial ● Note that this is the basic structure of a discrete trial used in establishing evoked baselines; if it is a treatment evoked trial, reinforce the client’s correct responses and give corrective feedback for incorrect responses
Exemplar.
An example of something; in treatment, a response that illustrates a target behavior; these may be words, phrases, sentences, gestures, and so forth; for example, the word soup is an exemplar if used in teaching the /s/ or /p/; thus, all words, phrases, and sentences used in teaching correct production of phonemes are exemplars; the sentence The boy is running is an exemplar if used in teaching the noun phrase, the auxiliary, or the main verb plus ing; thus, all phrases and sentences used in teaching language structures are exemplars; pictures and objects used in treatment also may be considered exemplars; an individual stimulus item designed to evoke a specific target response: ● Select multiple exemplars for each target behavior to be taught (e.g., 20 words to teach the /p/ in initial positions; 20 sentences that contain the regular plural s) ● Teach multiple exemplars of each target behaviors to enhance the potential for generalized production ● Probe after teaching a few (4 to 6) exemplars to see if generalized productions emerge with untrained stimulus items ● Teach more exemplars if the client does not meet the probe criterion (e.g., 90% accuracy of the target phoneme production in a set of 10 untrained words) ● Note that generalized production often results with a few exemplar training items (typically less than 10 exemplars) 247

Experiment. A controlled condition in which an independent variable (such as treatment) is manipulated to produce changes in a dependent variable (production of speech or language); a means of establishing cause-effect relations; needed to establish treatment effects; may use the Group Design Strategy or the Single-Subject Design Strategy.
Experimental Group. In a clinical experiment, the group that receives treatment and hence shows changes in skills taught; part of the Group Design Strategy for establishing treatment effectiveness; contrasted with a Control Group. ● Select participants randomly (Random Selection) ● Assign participants into control and experimental groups randomly (Random Assignment) ● Alternatively, match subjects in the experimental and control groups (Matching) ● Assess the experimental and control groups to make sure they are equal ● Treat the experimental group while withholding treatment to the control group ● Demonstrate that the experimental group changed (improved), whereas the control group did not
Expiratory Board. A prosthetic devise used to improve respiratory muscle strength for speech; client pulls a board attached to wheelchair toward his or her abdomen and leans against it to stabilize the muscles; often used in treating breathing problems associated with Dysarthria.
Exclusion Time-Out. Response-contingent exclusion of a person from a reinforcing environment; a variety of Direct Methods of Response Reduction; a form of Time-Out. 248
Expressive Aphasia ● Contingent on an undesirable behavior, remove the child
from the stream of activities (e.g., make the child sit outside the classroom or in a corner) ● Bring the child back to the stream of activities after a brief period of time ● Note that this procedure is generally not recommended because it takes time away from treatment ● Prefer nonexclusion time-out to exclusion time-out; in nonexclusion time-out, a brief period of silence (about 5 seconds) with no eye contact is imposed on an undesirable behavior; more efficient than removing the child from the stream of activities
Expressive Aphasia. Aphasia whose main characteristic is difficulty in expressive language and speech; a general term that suggests difficulty talking with no significant impairment in auditory comprehension; often refers to Broca’s aphasia.
Extension. A language treatment method in which the clinician makes comments on the child’s utterances to add additional meaning; for procedures, see Language Disorders in Children; Treatment of Language Disorders: Specific Techniques or Programs.
Extinction. A procedure to reduce undesirable response by terminating reinforcement for that response; similar to ignoring in everyday life; one of the Direct Methods of Response Reduction; use the following guidelines in implementing an extinction procedure: ● Factors that affect extinction; note that whether and how fast a behavior will be extinguished depends on the: • amount of past reinforcement for that response; a heavily reinforced response is more difficult to extinguish than the one reinforced less heavily • duration of reinforcement; a response reinforced for a longer duration may be more difficult to extinguish than the one reinforced for a short duration 249
E
Extinction
E
• previous exposure to reinforcement; a response that has been extinguished in the past will be more readily extinguished now than the one that is being extinguished for the first time ● Effective use of extinction in treatment session: • remove reinforcers for the response because this operation defines the procedure • educate the client’s significant others about extinction because parents find it difficult to watch their child’s behavior (e.g., crying) put to extinction; explain that other methods of temporarily stopping an undesirable behavior (e.g., picking up a child crying in a treatment session) may promote that behavior in future sessions • make an analysis of the reasons for the undesirable behavior you wish to extinguish; if it looks like it is maintained by attention, then withdraw attention; see Extinction of Positively Reinforced Behaviors; if it looks like the undesirable behavior helps the child avoid working hard in therapy (which is aversive to the child), then physically prevent such escape behaviors as crawling under the table when treatment trials are presented; see Extinction of Negatively Reinforced Behaviors; if it looks like the undesirable behavior is automatically reinforced (e.g., head banging), remove the sensory stimulation that results from such behaviors (e.g., make the child wear a padded helmet); see Extinction of Automatically Reinforced Behaviors • do not use extinction to control aggressive, self-destructive, and generally disruptive behaviors because extinction is a slow process and the response is allowed to be made with no reinforcers; allowing such responses to be made may result in injury to others and self; prevent the occurrence of such responses and use Differential Reinforcement to encourage alternative, desirable behaviors ● Note that extinguished responses recover sooner or later; when this happens, promptly extinguish again 250
Extinction of Reinforced Behaviors ● Note that some children may react very emotionally when
you start extinction; for instance, a child’s crying behavior may intensify when extinction is begun; do not give in at this point ● Combine extinction with positive reinforcement for a clearly stated alternative, desirable behavior (e.g., telling the child that ‘‘As soon as you stop crying, we can go out and see your mother’’ and following through)
Extinction of Automatically Reinforced Behaviors. The procedure of terminating automatic reinforcers for responses to be reduced; one of the Direct Methods of Response Reduction; especially useful in reducing self-stimulatory behaviors of clients who are autistic, profoundly mentally retarded, or brain injured because these behaviors are thought to be automatically reinforced by the sensory consequences they generate for those who exhibit them. ● Determine the sensory consequence of the undesirable behavior to be reduced (noise from banging on the table; stimulation from banging the head) ● Reduce or eliminate the sensory stimulation derived from the behavior to be reduced (cover the table with soft material or make the child wear a padded helmet) Extinction of Negatively Reinforced Behaviors. The procedure of terminating negative reinforcers for responses to be reduced; one of the Direct Methods of Response Reduction; also known as Escape Extinction; appropriate to reduce such behaviors as crawling under the table during treatment, leaving the chair and walking around the treatment room, interrupting treatment trials by suddenly interjecting ‘‘You know what?’’ types of responses, and grabbing the clinician’s pen or the stimulus material; such behaviors are exhibited because treatment trials are aversive to the child and the behavior provides escape from treatment work; the undesirable behavior is negatively reinforced because of such escape from aversive work; this escape needs to be prevented to stop reinforcement for it. 251
E
Extinction of Reinforced Behaviors ● Physically prevent the behavior; sit close to the child and
E
physically restrain when you see an early sign of the child leaving the chair; sit immediately opposite the child and hold the child’s chair between your legs; remove stimulus materials from the child’s reach ● Continue to present treatment trials ● Note that by preventing the escape behavior, you stopped its reinforcement as well; this is escape extinction ● Note that negatively reinforced undesirable behaviors cannot be extinguished by simply withdrawing attention
Extinction of Positively Reinforced Behaviors.
The procedure of terminating positive reinforcers for responses to be reduced; one of the Direct Methods of Response Reduction; appropriate to reduce such behaviors as crying maintained by reinforcement; should not be used to reduce aggressive, self-destructive, and generally disruptive behaviors, negatively reinforced behaviors, automatically reinforced behaviors, or behaviors that are due to physical pain and discomfort. ● At the very outset of extinction, tell the client that you will pay attention only when the undesirable behavior stops (e.g., say ‘‘As soon as you stop crying, I will take you out to see your mother.’’) ● Pay no more attention until the behavior stops; turn your back and sit motionless; do not try to use other means of stopping the behavior; do not peek at the child ● Do not be unnerved when the behavior initially intensifies (Extinction Burst); continue to ignore the behavior ● Pay immediate attention when the behavior subsides or stops (e.g., say ‘‘That is very good! You stopped crying; we can now go see your mother.’’)
Extinction Burst. A sudden, initial, and temporary increase in responses at the beginning of extinction; not a reason to abandon extinction when it is appropriately chosen.
252
Extraclinical Settings (Training In) Extraclinical Settings (Training In). Training given in such nonclinical settings as a playground, classroom, home, and other places; essential part of Maintenance Strategy; training is less formal, involving spontaneous, functional communication; often administered by such significant others as teachers, family members, and friends.
Extrapyramidal System. A neural pathway that carries motor impulses from the brain to various muscles via several relay stations; also called the indirect motor system; damage to this system may cause muscle tone problems and may affect voluntary movements of speech muscles; involved in Dysarthria; contrasted with the Pyramidal System.
Eye Contact.
Looking at the listener’s face during conversation; a pragmatic language intervention target; subject to ethnocultural variations, as in some cultures, eye contact between certain conversational partners (e.g., between a student and a teacher) may not be appropriate; for procedures, see Language Disorders in Children; Treatment of Language Disorders: Specific Techniques or Programs.
Eye Gaze.
A method of nonverbal communication often taught to individuals with severe neuromuscular impairment; a method of Augmentative and Alternative Communication; the client is taught to gaze at a word, a phrase, a symbol, or an object to convey a message.

Facilitated Communication Facilitated Communication. A once-popular technique
F
of language treatment for children with autism and others with severe language impairment in which a facilitator maintains physical contact with the hand, wrist, or elbow of the client to facilitate writing, typing, or pointing on a message board; controlled studies have produced negative evidence; results suggest that the facilitator may be the source of the messages typed; the American-Speech-LanguageHearing Association is not convinced of its effectiveness and recommends additional research; the American Psychological Association and the Association for Behavior Analysis have concluded that the method is ineffective and invalid; not recommended.
Factorial Stimulus Generalization.
Generalized production of unreinforced responses given in relation to new stimuli, settings, and audience; the most complex form of stimulus generalization. ● Use a variety of stimuli to evoke target behaviors ● Vary treatment settings ● Arrange different conversational partners for the client ● Probe for factorial stimulus generalization
Fading. A method of reducing the controlling power of such special stimuli as modeling and prompting while still maintaining the target responses the stimuli evoke. ● Reduce the frequency of the special stimulus (e.g., modeling) gradually ● Reduce the intensity of the stimulus (e.g., present Prompts in progressively softer voice until it is no longer provided) ● Present only a partial stimulus (as in Partial Modeling) ● Make the stimulus progressively more subtle (e.g., make the hand gesture given to slow down the speech of a person who stutters less and less conspicuous) ● Make a mechanical stimulus nonfunctional (e.g., turn off a microphone that the client still holds, or turn off a computer screen that remains in front of the client) 256
First Words ● Increase the distance from the client and the special stim-
ulus in graded steps (move the microphone or the computer screen away from the client)
First Words. The first few words a child typically acquires; language treatment targets for young children who are nearly nonverbal. ● Select child-specific words ● Select the names of family members, child’s favorite toys (car, doll), food items (milk, juice, candy), clothing items (sock, shoe), action verbs (come, go, walk), simple adjectives (big, small), animals (kitty, doggie), household objects (pen, book, spoon, chair, table), and words from similar categories ● Use the structured, Direct Language Treatment Approaches if the child is nearly nonverbal and has attention deficit: • use the Discrete Trials ● Use indirect language stimulation if the child interacts well and can concentrate on loosely structured treatment activities; use a play-oriented situation: • frequently model the target word productions • use the Mand-Model approach • use the Incidental Teaching Method ● Train parents to stimulate language at home; teach parents to: • have the child label an item before you hand it to him or her • read stories to the child and have the child name pictures • ask questions about the pictures (e.g., ‘‘How does the kitty go?’’) ● Give training in varied contexts and probe for generalized productions ● Move on to teaching Phrases (Word Combinations)
Fixed Interval Schedule (FI). An intermittent schedule of reinforcement in which an invariable time duration separates opportunities to earn reinforcers; the first response 257

Fixed Ratio Schedule (FR) made after the interval is reinforced; responses made during the interval are not reinforced; limited use in treating communicative disorders.
Fixed Ratio Schedule (FR).
F
A schedule of reinforcement in which a certain number of responses are required to earn a reinforcer; an FR1 in which every response is reinforced is a continuous schedule; schedules greater than 1 are intermittent; frequently used in treatment sessions. ● Specify the schedule to the client (‘‘I will give you a token every time you say it correctly.’’) ● Reinforce according to the specified schedule
Flaccid Dysarthria. A type of motor speech disorder caused by damage to the motor units of cranial or spinal nerves that supply speech muscles (lower motor neuron involvement). See Treatment of Dysarthria: Specific Types under Dysarthria.
Fluency. An aspect of speech and language production; quality or state of being fluent.
Fluency Disorders.
Speech disorders characterized by excessive amounts of dysfluencies, excessive duration of dysfluencies, or both; speech that is produced with excessive amounts of struggle and effort (Stuttering); speech that is characterized by excessively fast rate, indistinct articulation, and possibly language formulation problems (Cluttering); impaired fluency due to Neurogenic Fluency Disorders; Stuttering is the most researched and more frequently diagnosed and treated fluency disorder in the United States.
Fluency Reinforcement Techniques.
Reducing stuttering by increasing fluency through positive reinforcement; fluent intervals or fluent utterances may be reinforced through verbal praise or tokens that are exchanged for small gifts; can be effective in treating young children who stutter; for procedures see Stuttering, Treatment; Treatment of Stuttering: Specific Techniques or Programs. 258

A collection of stuttering treatment techniques based on the assumption that normalsounding fluency should be the intervention goal; include teaching such skills as airflow management, gentle onset of phonation, and reduced rate of speech through syllable prolongation; contrasted with Fluent Stuttering: Van Riper’s Approach; described under Stuttering, Treatment; Treatment of Stuttering: Specific Techniques or Programs.
Fluent Aphasia. A type of aphasia characterized by fluent but mostly meaningless speech full of neologistic words and jargon compounded by auditory comprehension deficits; contrasted with Nonfluent Aphasia; includes Wernicke’s aphasia, transcortical sensory aphasia, conduction aphasia, and anomic aphasia; see Aphasia and Treatment of Aphasia: Specific Types.
Fluent Speech. Speech that is smooth, flowing, effortless, and rapid within acceptable limits; negatively defined, it is speech that does not contain excessive amounts of pauses, repetitions, sound and silent prolongations, interjections, and other forms of dysfluencies; speech that is not produced with excessive effort and struggle; a treatment target for persons who stutter.
Fluent Stuttering: Van Riper’s Approach. A stuttering treatment approach based on the assumption that reduced abnormality of stuttering, not fluent speech, is a realistic goal for most persons who stutter; includes teaching such skills as cancellation, pull-outs, and preparatory sets along with counseling, desensitization, and stabilization of fluent stuttering; for procedures see Stuttering, Treatment; Treatment of Stuttering: Specific Techniques or Programs.

the first 6 months of dismissal, the next follow-up after 1 year, the next after 2 years) Take a speech-language sample Measure the frequency of the target behaviors (production of clinically established speech sounds, language structures, fluency or dysfluency, vocal qualities, etc.) Calculate the percent correct use of the clinically established target behaviors Give Booster Treatment if the target behaviors are below the previously set criterion (such as 90% accuracy)
Frequency of Occurrence of English Consonants. Use the following frequency of occurrence information in selecting treatment targets for children who misarticulate; note that frequency of occurrence is not an absolute criterion of selection; consider other factors as well (described under Articulation and Phonological Disorder); note that frequency suggests ranking based on the relative frequency of 24 English consonants (e.g., 16th for /p/ means that it ranks 16 in occurrence among the consonants); the lower the ranking, the higher the frequency; two different rankings for the same sound suggest discrepancy among studies: Sound Frequency

Functional Equivalence Training Delattre, P. (1965). Comparing the phonetic features of English, German, Spanish, and French. Heidelberg, Germany: Verlog. Shrieberg, L. D., & Kwiatowski, J. (1983). Computer assisted natural process analysis (NPA): Recent issues and data. Seminars in Speech and Language, 4, 397–406.
Functional Equivalence Training. An indirect method of reducing an undesirable behavior by reinforcing a desirable behavior that serves the same function as the undesirable behavior (e.g., teaching a verbal request to a nonverbal child who whines to get adult attention; the verbal request serves the same function as whining and thus is reduced in frequency); the same as the Differential Reinforcement of Alternative Behaviors (DRA); to implement this procedure: ● Find out the functions of an undesirable behavior that need to be reduced by analyzing: • the conditions under which an undesirable behavior occurs • the consequences it seeks (e.g., attention, reduction in needs, reduction in aversive stimulation, or sensory stimulation) ● teach a desirable, alternative behavior that is followed by the same consequence ● record the frequency of both the undesirable behavior (which should decrease) and the desirable (which should increase)
Functional Outcome Measures of Treatment. Measures that go beyond counting the correct production of specific target behaviors in treatment sessions; often involve qualitative measures of overall changes in the client’s behaviors; measures of changes in the client’s quality of life; measures of generalized production of communicative skills in natural environments; measured that are based on rating of communicative effectiveness of clients in everyday situations;

F
Functional Outcome of Treatment Functional Outcome of Treatment.
F
Generalized, broader, and socially and personally more meaningful consequences of treatment; measured in more global terms than the effects measured in treatment sessions ● Document functional outcomes of treatment by measuring: • improvement in certain quality aspects of life of a client that may be due to treatment (e.g., improved social or academic performance of a child who has received language treatment; an adult’s return to work after receiving rehabilitation services following traumatic brain injury; a stuttering male’s improved dating skills or his enhanced communicative skills with his boss at work) • generalized and effective production of clinically established communicative skills in social, personal, family, educational, and occupational contexts; note that minimally, clients should produce at home and other settings what they have been taught to produce in the clinic • functional communication in natural settings (e.g., effective expressions of needs and wants by persons who have received treatment for aphasia; managing daily communication needs by a child who has received augmentative or alternative communication therapy; effective use of a hearing aid in social situations and documented benefits derived by a person who has received aural rehabilitation) • expansion of clinically established skills in natural settings (e.g., new and longer sentences produced in natural settings by a client who has received language treatment) ● Obtain information on functional outcomes from institutional caregivers and family members by: • interviewing them on different domains of skills and communicative behaviors • having them rate a client’s communicative effectiveness in natural contexts ● Note that functional outcomes
262
Functional Outcome of Treatment • are not the same as Effectiveness of Treatment; treatment effectiveness is established in controlled experimental research • are simply measured changes in the client’s communicative behaviors in natural settings; favorable outcomes, if documented, may be due to any factor including the family involvement, caregiver attention, and so forth; it cannot be claimed that treatment was effective • outcomes research makes sense only after the effectiveness of a treatment is established

apy with an emphasis on voice therapy designed for individuals who, at some point in their lives, assume a different gender; speech-language pathologist may be asked to help achieve proper gender identification after the change. ● Note that voice modification in a woman who has changed to a man may be achieved by hormone treatment that will thicken the vocal folds and lower the pitch ● Note that voice modification in a man who has changed to a woman may require extensive voice therapy, as the medical treatment to achieve an overall female pitch has met with limited success; also note that just a higher pitch may not be sufficient; the client may need to learn overall female speaking patterns • make a thorough assessment of the entire vocal range; identify a pitch that is appropriate, comfortable, and is not associated with laryngeal tension • use biofeedback or computerized programs to have the client practice the new pitch • teach stereotypically feminine intonation patterns (e.g., rising intonation at the end of sentences that characterize female speech) • discourage falsetto voice • teach the person to speak with more mouth openness, more air, and ‘‘placing’’ the voice in the head and face (presumably, men place their voice in the head) • teach the client to speak more softly than before • teach the client to speak slightly faster and with increased pause durations as these are characteristics of female speech • teach a more precise articulation of speech sounds 266
Gender Reassignment • teach the client to use more indirect speech and indirect requests (e.g., ‘‘Do you mind doing . . .’’ instead of ‘‘Do this’’ type of command) • teach the client to emphasize feelings and relationships as against facts in speech • teach female body language (more smiling, touching, eye contact) • avoid such masculine habits of throat clearing and coughing Andrews, M. L. (1999). Manual of voice treatment (2nd ed.). San Diego: Singular Publishing Group.
Gender Reassignment. Sex change; someone who has been living as a man may now become a woman or vice versa through a sex-change operation; he or she may seek communication treatment to achieve the new and intended gender identity.
Generality of Treatment. The applicability of a treatment procedure in a wide range of situations involving other clients and clinicians; demonstrated through Replication of treatment efficacy research; a Treatment Selection Criterion: ● Select treatment procedures that are known to have generality; consider the following kinds of generality in evaluating and selecting a treatment procedure: • applicability of a treatment procedure by a wide variety of clinicians; has the technique been effectively used by different clinicians? • applicability of a treatment procedure in a variety of clients; is the treatment procedure known to be effective with clients of different ages, socioeconomic conditions, educational levels, and ethnocultural backgrounds? • applicability of a treatment across clinical settings; is the treatment known to be effective in such varied clinical settings as a private clinic, hospitals, university speech and hearing clinics, extended care facilities, and rehabilitation facilities? 267

Generalization
G
• applicability of treatment across geographic settings; is the treatment known o be effective in clinical facilities across the country? • applicability of treatment across response classes; is the treatment known to be effective in treating a variety of disorders? (e.g., techniques such as modeling and reinforcement, known to be effective in speech and language treatment, may be equally effective in treating disorders of swallowing) ● Note that effectiveness of treatment implies experimental evaluation; existence of controlled data showing that treatment is better than no treatment; just because a technique is widely used in different clinics by different clinicians, in different geographic locations, and in treating different clients is no assurance that the technique is effective; no amount of expert advocacy in the absence of controlled data should convince clinicians to use a technique routinely
Generalization. A declining rate of unreinforced responses in the presence of untrained stimuli; a temporary, intermediate goal of treatment; includes Verbal Stimulus Generalization, Physical Setting Generalization, Audience Generalization, Factorial Stimulus Generalization, and Response Generalization; each may be promoted with specific techniques; see Maintenance Strategy to promote lasting treatment effects.
Generalized Production. Production of clinically established behaviors in relation to new stimuli, new audiences, and in new situations; measured through Probes.
Genetic/Neurophysiological Contingency. The interdependent relation between genetic and neurophysiological variables that determine or influence behaviors; contingency that interacts with Environmental Contingency.

Gestural Communication dures see Stuttering, Treatment; Treatment of Stuttering: Specific Techniques or Programs; and Voice Disorders, Treatment of Voice Disorders.
Gestural Communication.
Method of communication that supplements oral communication with smiles and a variety of other facial expressions, body movements including shoulder shrugging, hand movements, pantomime, pointing, and head nodding or shaking; part of normal oral communication; in gestural communication, expressions are important in communicating the speaker’s messages; gestural communication may be unaided as in smiling or hand movements; or aided, as in gestures combined with a communication board; procedures described under Augmentative Communication, Gestural (Unaided) and Augmentative Communication, Gestural-Assisted (Aided).
Glossectomy. Partial or total surgical removal of a diseased or severely damaged tongue.
Glottal Fry. A normal voice register that may occur at the end of sentences; very low-pitched vocalization that may sound like the popping of popcorn; also called vocal fry.
Gradient of Generalization. Progressively decreasing, unreinforced response rate as a stimulus is varied on a given dimension, resulting in a curve that approximates the bellshaped curve; the reason why generalization is not a final treatment goal.
Gradual Increase in Length and Complexity of Utterances (GILCU). A component of the Monterey Fluency Program; for procedures see Stuttering, Treatment; Treatment of Stuttering: Specific Techniques or Programs.
Granulovacuolar Degeneration. A build-up of fluidfilled vacuoles and granular remains within nerve cells; a basic neuropathology of Alzheimer’s Disease and found in some normal elderly people. 269

Group Design Strategy Group Design Strategy.
G
A research strategy in which the experimental treatment effect or efficacy is demonstrated by treating individuals in one group (the experimental group) and not treating individuals in another, comparable group (control group); helps demonstrate that treatment was better than no treatment; one of two strategies for treatment evaluation; contrasted with Single-Subject Design Strategy. ● In implementing a basic control-group/experimentalgroup treatment research in which a single treatment is evaluated: • identify a population (a large number of subjects with known characteristics) of participants with the disorder for which the treatment to be evaluated has been designed • select a sample of participants randomly from the population • randomly assign the participants to an experimental and a control group • match participants in the two groups on relevant variables if random selection and assignment are not possible, • administer pretests of the disorder (or measure specified skills) in the two groups • treat participants in the experimental group • withhold treatment from the control group • administer posttests of the disorder (or measure specified skills) in the two groups • compare the performance of the two groups on the pretest and the posttest • conclude that the treatment was effective if the experimental group improved while the control group did not ● In evaluating the absolute and relative effects of multiple treatments: • use multigroup experimental designs in which two or more groups receive treatment (each group receives only one treatment) 270
Group Design Strategy ● In evaluating interaction between treatments and per-
sonal characteristics of clients (e.g., Does age of the clients matter in the effectiveness of a given treatment?): • use factorial designs that help establish the relative effectiveness of treatments depending on such personal characteristics as age, socioeconomic factors, and the severity of the disorder Hegde, M. N. (1994). Clinical research in communicative disorders: Designs and strategies (2nd ed.). Austin, TX: Pro-Ed.

Hard Glottal Attack Hard Glottal Attack.
H
Abrupt voice initiation with too much stress on individual words; words of a sentence sound too separated; a vocally abusive behavior; also found in persons who stutter. ● Teach gentle, relaxed, easy onset of phonation ● Teach the client to blend words initially ● Teach gentle onset in persons with stuttering by instructions and modeling ● Use the Chewing technique, Whisper-Phonation, the Chant-Talk, and the Yawn-Sigh, all described under Voice Disorders, Specific Normal Voice Facilitating Techniques to treat hard glottal attacks in voice clients ● Contrast the easy-onset production with a hard-onset production to treat all clients with this problem
Hard of Hearing. Persons who have reduced hearing acuity but nonetheless are able to acquire, produce, and comprehend language primarily with the help of audition; may use amplification and visual cues to understand speech.
Harshness. Voice quality that results from excessive laryngeal tension, effort, and constriction. ● Use relaxation to reduce vocal tension ● Teach soft, easy contact of the vocal folds ● Teach gentle onset of phonation ● Use a combination of Specific Normal Voice Facilitating Techniques described under Voice Disorders
Hearing Aid. Electronic device that amplifies sound and is prescribed for individuals with hearing impairment; may be of analog or digital variety; types include body-worn, behind-the-ear (BTE), eye glass, in-the-canal (ITC), in-the-ear (ITE), or completely in-the-canal (CIC).
Hearing Aid Evaluation. An aural rehabilitation procedure in which different kinds of hearing aids are tried to make a selection of an aid that best fits the hearing loss profile and gives the most benefit to the client.
274
Hearing Aid Orientation Hearing Aid Orientation. An aural rehabilitation procedure in which the use and care of a hearing aid is taught to a person with hearing impairment.
Hearing Conservation. A program designed to prevent or reduce the risk of hearing loss; includes procedures to monitor hearing over a period of time and to educate the client, family, employers, and employees about protecting their hearing.
Hearing Impairment. Reduced hearing acuity; a hearing level that is greater than 25 dB HL for adults and 15 dB HL for young children in the process of language acquisition; includes the Hard of Hearing and the Deaf; classified as shown under Hearing Loss; oral speech and language disorders are a common concomitant of hearing impairment, especially deafness; mostly, the treatment procedures for Language Disorders in Children, Articulation and Phonological Disorders, and Voice Disorders are applicable with the following special considerations:
General Guidelines
● Begin speech and language stimulation training as early as
possible
● Have the child under appropriate medical and audiological
management
● Get the family involved from the beginning in speech and
language stimulation activities
● Have the child fitted with an individual hearing aid ● Work closely with educators and special educators, espe-
cially the educator of the deaf
● Train family members to work with the child at home con-
ducting sessions that parallel yours Teaching Oral Language ● Begin oral language training as early as possible ● Teach the basic words initially; select functional words ● Teach phrases and sentence structures subsequently
275
H
Hearing Impairment ● Pay special attention to teaching grammatic mor-
H
phemes, as they are especially difficult for children with hearing impairment ● Pay special attention to pragmatic use of language, as it is especially difficult for children with hearing impairment; teach such skills as Topic Initiation, Topic Maintenance, and Turn Taking described under Language Disorders in Children; Treatment of Language Disorders: Specific Techniques or Programs. ● Pay special attention to teaching abstract terms, terms with dual meanings, and the meaning of proverbs, as they are especially difficult for children with hearing impairment ● Pay special attention to teaching synonyms and antonyms, as they are especially difficult for children with hearing impairment ● Use visual cues in all training sessions ● Refer to specialists who can teach such nonverbal communication systems as American Sign Language if the clients, families, or both prefer Teaching Articulatory Skills ● Give ample visual cues in teaching speech sound production ● Use such procedures as the Phonetic Placement Method ● Pay special attention to fricatives, stops, and affricates, as these are especially difficult for children with hearing impairment ● Teach voiced and voiceless sound distinctions ● Use mechanical visual feedback Treating Voice Disorders ● Use the standard techniques described under Voice Disorders ● Use mechanical, visual feedback with such instruments as VisiPitch ● Modify such abnormal voice qualities as harshness, hoarseness, stridency, and monotone 276
Hearing Loss ● Modify resonance disorders; modify both hypernasal-
ity and hyponasality Treating Prosodic Problems ● Teach smooth flow of speech ● Reduce pauses that may be too frequent and placed inappropriately ● Teach normal intonation ● Teach appropriate breath control to improve phrasing ● Modify the pitch ● Modify loudness
Hearing Loss. Roughly the same as Hearing Impairment; classified as follows: ● Mild hearing loss: 15–40 dB HL Moderate hearing loss: 41–70 dB HL Severe hearing loss: 71–90 dB HL Profound hearing loss: 90 dB and higher
High Probability Behaviors. Behaviors of high frequency that can reinforce those of low frequency; an effective treatment method to increase low frequency treatment targets. ● Identify behaviors your client exhibits frequently (e.g., listening to music, watching television, or skiing) ● Design a method by which you in the treatment sessions and the family members at home can control opportunities for those behaviors ● Give tokens in treatment sessions for producing the lowfrequency communicative skills ● Let the client accumulate the tokens and exchange them for opportunities to engage in the high-probability behaviors (brief periods of listening to music in treatment sessions, watching TV at home, or going on ski trips)
Hoarseness. Voice quality that results from leakage of air and aperiodic vibration of the vocal folds; pitch may be too low; any condition that changes the mass and size of the vocal folds, including vocal nodules, may cause hoarseness of voice. 277
H
Huntington’s Disease ● Obtain a medical evaluation and clearance before starting
voice therapy
● Modify the vocally abusive behaviors ● Use a combination of Specific Normal Voice Facilitating
Techniques, described under Voice Disorders.
Huntington’s Disease. An Autosomal Dominant, degen-
H
erative neurological disease; caused by neuronal loss in the caudate nucleus and putamen along with diffuse neuronal loss in the cortex; symptoms include Choreiform Movements and Dementia; associated with motor speech disorders and language impairment; general management procedures described under Dementia.
Hyperadduction.
Closure of vocal folds with excessive force and tension. ● Teach laryngeal relaxation ● Teach breathy onset of phonation ● Teach gentle, relaxed, easy phonatory onset ● Massage the larynx ● Use such other specific normal voice facilitation techniques as the Yawn-Sigh Method and the Chewing Technique described under Voice Disorders; Specific Normal Voice Facilitating Techniques.
Hyperkeratosis.
Keratotic lesions in the pharynx or larynx; a pinkish, rough lesion with horny growth; associated with Voice Disorders; nonmalignant in the initial states; may be a precursor to malignant lesion; due to continued irritation of tissue, including chronic smoking; treatment is to stop behaviors that result in continued irritation (e.g., cessation of smoking).
Hyperkinetic Dysarthria. A type of motor speech disorder; its neuropathology is damage to basal ganglia (extrapyramidal system) resulting in rapid involuntary movements and variable muscle tone; may affect all aspects of speech, but a dominant symptom is prosodic disturbances; see Hy278
Hypernasality perkinetic Dysarthria, under Treatment of Dysarthria: Specific Types.
Hypernasality. Nasal resonance on nonnasal speech sounds; a resonance disorder; intervention described under Voice Disorders; Treatment of Disorders of Resonance.
Hypertonia. Excessive muscle tone or tension; a sign of neurological damage; a symptom in many clients with neurogenic communication disorders (e.g., cerebral palsy, dysarthria).
Hypoadduction. Inadequate approximation of vocal folds; results in breathiness and weak voice; often associated with neurological involvement; a symptom found in such neurogenic communication disorders as Dysarthria and Voice Disorders due to vocal fold paralysis. ● Elicit coughing, grunting, throat clearing, and laughing to improve Adduction ● Use Digital Manipulation of the Larynx described under Voice Disorders; Specific Normal Voice Facilitating Techniques; use this technique along with pressure applied to the abdominal muscles to increase subglottic pressure ● Teach pushing, pulling, and lifting exercises and combine them with phonation; see Dysarthria
Hypokinetic Dysarthria. A type of motor speech disorder; its neuropathology is damage to basal ganglia (extrapyramidal system) resulting in slow movement, limited range of movement, and rigidity; may affect all aspects of speech, but especially voice, articulation, and prosody; see Hypokinetic Dysarthria under Treatment of Dysarthria: Specific Types.
Hyponasality. Reduced or absent nasal resonance in the production of nasal sounds; the same as Denasality; intervention described under Voice Disorders; Treatment of Disorders of Resonance.
Hypotonia. Reduced tone or tension. 279

IEPs (Individualized Education Programs). Childspecific intervention programs designed for children with disabilities or special needs served in public grade schools. ● Assess the child’s communicative strengths and weakness ● Write an IEP for each child you serve; consult with teachers and special educators to include specific goals and objectives they suggest ● State the short- and long-term intervention objectives in measurable terms ● Describe the frequency and duration of your intervention sessions ● Specify the amount of time the child will spend in regular classroom ● Specify the intervention initiation and termination dates ● Justify the need for your services (use the school district’s guidelines in determining service eligibility) ● Specify the names of special education or other professionals who also will serve the child ● Talk to family members to get their input and approval of treatment goals ● Hold an IEP meeting to finalize the intervention plan and to get the signatures of all attending, including those of the parents ● Make periodic assessment of the child to see if the goals are being met and to evaluate whether the goals or treatment procedures need to be modified 282
Individualized Family Service Plans IFSPs (Individualized Family Service Plans). Special education programs designed for children with disabilities in the age range of birth through 2 years and their family members. ● Develop a plan similar to IEPs ● Include information on the family’s needs and strengths ● Orient the plan toward family involvement
Imitation. A response that follows a modeled stimulus and takes the same or similar form of its stimulus; frequently used in the beginning states of treatment of most if not all communicative disorders; Modeling is the treatment technique to evoke imitation; to teach imitative responses: ● Model the correct response for the client; use instructions and demonstrations as found appropriate ● Place extra vocal emphasis on the specific target behavior in a modeled utterance (e.g., ‘‘Say two cups,’’ with an emphasis on the grammatic morpheme in teaching the regular plural productions) ● Reinforce the client for imitating the modeled response ● Reinforce approximations initially, especially in the treatment of correct articulation of phonemes ● Require greater match to the modeled response in successive trials ● Fade modeling gradually to transition to evoked responses
Imitation of Aversive Control. Use of aversive methods to control others by persons who were subjected to aversive control themselves; a potential, undesirable sideeffect of punishment procedures; a reason to limit punishment procedures in treatment by using strong positive reinforcement techniques for desirable target behaviors.
Imposition of Work. One of the Direct Methods of Response Reduction in which an undesirable behavior is reduced by immediately imposing work designed to reduce or eliminate the negative effects of that behavior; also known 283
I
Improvement as overcorrection; has two components: restitution and positive practice.
Restitution
● Immediately following an undesirable behavior (e.g.,
I
throwing toys around), ask the child to neutralize the effects of that behavior (pick up the toys) ● Ask the child to go beyond neutralizing the effects of his or her behavior by improving the situation (ask the child to put the toys on a shelf and then clean up the mess created by another child)
Positive Practice
● Ask the child to practice an incompatible, appropriate be-
havior repeatedly without reinforcement (ask the child to organize your stimulus materials)
Improvement. Documented positive changes in the client’s behaviors compared to initial assessment or baseline performance; needed to justify treatment; what a clinician can claim when routine treatment is offered; not the same as Effectiveness of Treatment, which requires controlled experimental evidence that demonstrates that treatment was better than no treatment.
Incidental Teaching Method. A naturalistic language treatment method that uses everyday verbal interactions to teach functional communication skills; procedure described under Language Disorders in Children; Treatment of Language Disorders: Specific Techniques or Programs.
Incompatible Behaviors. Behaviors that cannot be produced simultaneously, such as sitting and walking; used to reduce certain undesirable behaviors; targets in the Differential Reinforcement of Incompatible Behaviors (DRI).
Independent Variables. Hypothesized or demonstrated causes of events scientists investigate; treatment methods clinicians use; anything a clinician does that affects the client’s behavior, including instructions, modeling, demonstration, 284
Indirect Language Stimulation positive reinforcement, and corrective feedback; contrasted with Dependent Variables.
Indirect Language Stimulation. A collection of somewhat varied, naturalistic, unstructured, or minimally structured language stimulation procedures based on play activities with no systematic reinforcement for specified target behaviors; for procedures, see Language Disorders in Children; Treatment of Language Disorders: Specific Techniques or Programs.
Indirect Methods of Response Reduction. Reducing certain behaviors by increasing other behaviors; indirect because no contingency is placed on behaviors to be decreased; in many cases, more desirable than the direct methods of response reduction because they avoid negative side effects of punishment; include Differential Reinforcement of Alternative Behavior, Differential Reinforcement of Incompatible Behavior, Differential Reinforcement of Low Rates of Responding, and Differential Reinforcement of Other Behavior.
Indirect Treatment for Swallowing Disorders. Treatment of swallowing disorders in which food is not presented to the patient; mostly involves various kinds of exercises; see Direct Treatment for Swallowing Disorders.
Informative Feedback. Information provided to the client on his or her performance levels that reinforces clinical target skills; may be verbal or mechanical; contrasted with Mechanical Corrective Feedback, Nonverbal Corrective Feedback, or Verbal Corrective Feedback in which the information provided is specific to the wrong responses to be decreased.
Verbal
● Periodically, tell the client how well he or she is doing (e.g.,
‘‘You have improved to 85% today.’’)
● Show and describe charts and graphs that depict increases
in target skills 285
I
Infrared Systems Mechanical
● Display positive changes and improvement data on com-
puter monitors and other display devices
Infrared Systems. A variety of Assistive Listening Devices that includes a transmitter that transmits messages on light pulses to a receiver worn by a person with hearing impairment; useful in such large listening environments as concert halls and classrooms.
I
Inhalation Method. A method of air intake to produce esophageal speech; for procedures, see Laryngectomy; Treat Esophageal Speech.
Inhalation Phonation. A technique of voice therapy to evoke true vocal fold vibration in clients who are aphonic; for procedures, see Voice Disorders, Specific Normal Voice Facilitating Techniques.
Initial Response. The first, simplified component of a target response used in Shaping.
Injection Method. A method of air intake to produce esophageal speech; for procedures, see Laryngectomy; Treat Esophageal Speech.
Instructions. Verbal stimuli that promote the production of target responses; often used in treatment sessions; combined with Demonstrations, Modeling, and Manual Guidance (as in Phonetic Placement Method) ● Design instructions that clarify the target behavior for the client ● Simplify your instructions and tailor them to the individual client ● Write your instructions and practice their delivery, but deliver them naturally; do not read them ● Repeat instructions until the client understands them ● Combine them with demonstrations, modeling, and manual guidance 286
Intelligibility Intelligibility. The degree to which a speaker’s speech is understandable to others; impaired for various reasons, but typically will be inadequate articulation of speech sounds; a treatment target in treating speech disorders in a variety of clients including children with articulation disorders and adults with dysarthria.
Intelligibility Drills. A method to help improve intelligibility of speech in speakers who have Dysarthria.
● Prepare a list of words that contain many target sounds
the client has difficulty with
● Ask the client to read the list aloud ● Turn back from the client to judge the accuracy of speech
sound productions based only on phonatory cues
● If the production of a sound is unclear, ask the client to
find out why and try again
● If this second attempt also fails, turn around, look at
the printed word, and give corrective feedback to the client ● Ask the client to try saying the same word again Yorkston, K. M., Beukelman, D. R., & Bell, K. (1988). Clinical management of dysarthric speakers. San Diego: College-Hill Press.
Intention Tremor. Tremor that is absent during periods of rest, but manifests itself during voluntary movements.
Interdisciplinary Teams. Teams of different specialists who assess and design treatment programs for clients; typically headed by one specialist; members finalize assessment and treatment plans after one or more meetings.
Interfering Behaviors. Behaviors that interrupt the treatment process; includes such behaviors as leaving the chair, asking irrelevant questions during treatment, crying, wiggling in the chair, and inattentiveness; sometimes a priority focus for clinical intervention because speech-language behaviors cannot be trained unless such interfering behaviors are reduced or eliminated. 287
I
Intermediate Care ● Use one of the Differential Reinforcement procedures to
increase the alternative desirable behaviors, which will then reduce the interfering behaviors
Intermediate Care. A health care facility where persons with disability or chronic illness needing long-term care are admitted; facilities that persons enter after they have been discharged from a hospital and still need professional care.
Intermediate Response. Responses other than the initial
I
and the final responses used in Shaping a target skill.
Intermittent Reinforcement. Several schedules of reinforcement in which only some responses or responses produced with specified delay are reinforced; produces stronger response rates than Continuous Reinforcement; includes the Fixed Ratio, Fixed Interval, Variable Ratio, and Variable Interval Schedules; useful in promoting response maintenance over time; to be used in the intermediate and final strategies of treatment, as it is not very effective in establishing the target responses.
Intermixed Probes. Procedures used to assess generalized production of a trained skill by alternating trained and untrained stimulus items; alternating trained and untrained stimuli helps prevent extinction of trained responses because responses given to trained stimuli are reinforced (those given to untrained stimuli are not); see Articulation Disorders for an example. ● Have at least 10 items not trained (e.g., 10 words or phrases with the plural s when this grammatic morpheme is the treatment target; 10 words or phrases with /z/ in the medial position when this phoneme is the treatment target) ● Prepare a Probe Recording Sheet on which you have alternated trained and untrained exemplars; have at least 10 untrained exemplars that may be words, phrases, or sentences used in training phonemes or grammatic morphemes 288
Intersystemic Reorganization ● Present a trained exemplar on the first trial (e.g., the pic-
●
● ● ● ●
ture of two cups if this word has been trained); evoke the response by asking a question (e.g., ‘‘What are these?’’); reinforce the correct production Present an untrained exemplar on the second trial (e.g., the picture of two books, a stimulus item not used in training); ask a question to evoke the response; provide no reinforcement or corrective feedback Alternate trained and untrained exemplars on the subsequent trials Calculate the percent correct probe responses based only on responses given to the untrained exemplars Give additional training when an adopted probe criterion is not met (e.g., 90% accuracy) Move on to next level of training or to new target behaviors when the criterion is met

Use of certain gestures, manual signs, or rhythmic and unusual movements (e.g., tapping, pantomiming, AMER-IND gestures or idiosyncratic gestures a patient invents) to facilitate speech production; often used in the treatment of patients with aphasia. ● Select a set of simple, easily recognizable gestures for the client (e.g., cupping the hand behind the ear to suggest ‘‘speak louder’’; or select AMER-IND gestures to suggest specific meanings) ● Teach the client to produce the gesture and understand its meaning; use modeling and manual guidance of the gestural movements; educate the client about the meaning of the gesture if it is not clear; make sure the client can use them reliably and communicatively ● Combine the gesture with speaking; model both the gesture and the verbal expression that goes with it; have the client imitate both in combination; when the client is producing the combination, simultaneously model them or 289

the component on which the client falters; use manual guidance (molding the patient’s hands to form the gesture) Teach the gesture-speech combination outside the clinical setting to promote its generalized productions in natural settings Fade the gestures if only the speech can be maintained Teach the client to self-cue verbal expression with the help of gestures (in which case, the gestures are not completely faded, but retained at a reduced form and rate to help get the verbal expressions going) Do not use this procedure with severely aphasic clients who cannot learn to gesture or to combine gestures with speech

Intervention.
Introduction and manipulation of external variables to affect the course of a disorder, disease, problem behavior, or condition with a view to eliminate the condition or effect positive changes; the same as treatment.
In-the-Ear Hearing Aid. A small hearing aid that fits within the ear canal and concha.
Intonation. Variations in pitch that give speech a pleasant melodic quality; a normal aspect of speech; a treatment target in many clients with communication disorders or when stutter-free speech is instated with slow speech that results in monotonous speech.

Intubation Granuloma. A lesion of the larynx that occurs at or near the vocal process of the arytenoid because of trauma caused by the insertion, positioning, or removal of an endotracheal tube; treatment is surgical; no voice therapy except for vocal rest. 290
Isolated Therapy Model Isolated Therapy Model. A special education service delivery model in which children are taken out of the classroom for special instruction, including speech-language instruction; the same as the Pull-Out Therapy Model.
Isolation Time-Out. Response-contingent removal of a person from a reinforcing environment and placing him or her in a nonreinforcing environment; a variation of TimeOut; involves physical isolation (such as placing the person in an isolation booth); may be considered only in reducing highly abusive, aggressive, or self-destructive behaviors; not especially useful in communication treatment sessions; misuse of this technique is common in educational settings; Nonexclusion Time-Out is preferred.

Language Delay in Children. Generally the same as Language Disorders in Children, except for the connotation that children with language delay are slow in learning and that they will catch up with their normally progressing peers; language disorders in children tend to persist; hence, disorders and delay are not synonyms; treatment procedures the same as those for Language Disorders in Children.

Language Disorders in Adults. Difficulty in comprehending, formulating, and producing language; often there is a history of normally acquired and used language functions; loss of language functions often are due to physical diseases, especially neurological diseases; includes Aphasia, Apraxia, Dementia, Dysarthria, and language disorders associated with Right-Hemisphere Syndrome and Traumatic Brain Injury.
Language Disorders in Children. Difficulty in learning to comprehend and/or produce language in a varied group of children, some of whom have associated clinical conditions whereas others show no such conditions; also referred to as Language Delay, Language Disabilities, Language Deviance, Language Impairment, Language-Learning Disorders, and Language Problems; the term Childhood or 298
Lang. Dis./Children: Ethnocultural Congenital Aphasia is dated and controversial; the term Specific Language Impairment refers to a special group of children with language problems with no other difficulties, and is also controversial.
Ethnocultural Considerations in Treating Language Disorders in Children ● Language is not just a linguistic code, it is a part of
cultural heritage • language should not be divorced from culture and society; excessive emphasis on language as a linguistic code with universal rules violates the true nature of language and communication • a child’s language should be understood in the context of his or her culture ● Language may have some universal commonalities, but it is not spoken in a uniform manner • universal rules of language should not be overemphasized; diversity and variations in languages structure are closely related to diversity and variations in people who speak them • certain common linguistic rules of language should not be misinterpreted to mean certain standards all should follow ● A client’s language performance should not be compared against norms established for another cultural community • each child’s language should be evaluated against the cultural practices of the community to which the child belongs • the typical practice of routinely comparing a child’s performance on some language measure to that of a typical group to which the child does not belong is inappropriate • the practice is even more objectionable when a standardized test that did not include members of the group to which the child belongs in its standardization 299
L
Lang. Dis./Children: Ethnocultural
L
procedure is used to evaluate treatment effects or the child’s progress in treatment ● Language differences go beyond just linguistic differences; cataloging linguistic differences is not sufficient; to understand it, you need to understand the culture of the client • multicultural literature in the past has often emphasized linguistic differences among languages; while these differences are important, the clinician needs to go beyond them • linguistic differences, after all, are a part of the larger cultural differences ● Defining language as a form of social behavior is immensely useful; such a definition implies that people’s languages are as unique and different as their social behaviors are • viewing language as a form of social behavior deemphasizes the universal code notion of language promoted by structural linguists of the past • viewing language as a form of social behavior forces us to pay attention to cultural and social forces that shape patterns of communication ● Stereotyping ethnocultural groups is the same as not understanding them; individuals conform to their group norms to varying extents, and some do not conform at all; for instance, individuals of a particular ethnocultural group: • do not always dress like the traditional members of their group • do not always eat the foods of their group • do not always socialize among themselves • do not always share the religious beliefs of their traditional culture • do not necessarily reject the values of other ethnocultural groups
300
Lang. Dis./Treatment: Guidelines ● Selecting language treatment targets for ethnocultur-
ally diverse children; this requires a knowledge of the child’s language characteristics and his or her cultural communication patterns; selected targets should be consistent with the child’s dialectal variation; a feature that is a part of the child’s language, but conflicts with another group norm should not be a target for modification; information on treating certain culturally diverse groups in the United States is now accumulating; see Treatment of Language Disorders in African American Children and Treatment of Language Disorders in Bilingual Children following the next major entry.
Treatment of Language Disorders in Children: General Guidelines Several issues are relevant to the target behavior selection process. Consider the following: ● Selection of Target Behaviors • normative strategy, which requires clinicians to select target behaviors based on language development norms; a child with a language disorder does not meet the normative expectations; therefore, the skills that are missing from the standpoint of norms are considered the treatment targets • client-specific strategy, which emphasizes functional targets; accordingly, target behaviors should be childspecific; in selecting target behaviors for a child, his or her family and educational demands, family communication patterns, and the behaviors that, when taught, will make a difference, need to be considered; this view is more consistent with the functional view of language treatment and preserves the notion of uniqueness of each individual ● Sequencing the Language Targets for Treatment • normative strategy, which requires that selected target behaviors should be sequenced according to the
301
L
Lang. Dis./Treatment: Guidelines
L
developmental norms; behaviors should be taught in the sequence in which children normally acquire them; although some behaviors may be more efficiently taught this way, there is no compelling evidence that this is always the best approach to sequencing target behaviors; rarely put to the test because of the strong assumption that this is the best • experimental strategy, which encourages clinicians to experiment with different sequences of teaching the target behaviors and then using the one that produces the best results; the data may show that normative sequence is indeed the best or that other sequences are better or just as good ● Structure of Language Treatment Sessions • tightly structured sessions, which are preferred by some clinicians; tend to involve discrete trial teaching; the clinician controls the stimuli and response consequences; tend to have clearly defined target behaviors for teaching; measurement oriented • loosely structured sessions, which are preferred by some clinicians; tend to involve play-oriented sessions; the clinician does not directly control stimuli and consequences; tend not to have clearly specified target behaviors that are taught systematically; not very measurement oriented • the two options are perhaps not a matter of choice; the best approach might be to use them both but in different stages of treatment; the early stages of treatment are better structured to establish the target behaviors; the final stages of treatment should be less structured, more naturalistic, more conversationoriented, and thus loosely structured; starting with good structure, clinicians should loosen the structure as behaviors become better established
302
Lang. Dis./Comprehensive Treatment ● Treatment Efficacy
• there are many language treatment procedures that have rarely been put to experimental test; techniques that are simply based on expert advocacy should be viewed critically • evidence-based practice requires that treatment procedures that have received experimental support should be selected; most behavioral treatment procedures have been experimentally tested; many suggestions that come from structural linguists and (some clinicians as well) are based on speculation and theoretical convictions; see Treatment Selection Criteria
Treatment of Language Disorders in Children A Comprehensive, Integrated, Treatment Procedure for Language Disorders in Children ● Make a complete assessment based on an extended conversational speech and other culturally sensitive assessment tools; consult the cited sources and the PGASLP ● Determine what the child can and cannot do with language (comprehension and production; structures the child understands and uses and those that the child does not understand or use) ● Follow these steps in developing a language treatment plan for a child: • select target behaviors for training • plan a sequence of treatment • select stimulus materials • establish baselines • write a treatment and maintenance plan • implement the treatment plan • implement the maintenance plan ● Select language intervention targets that: • are child-specific and ethnoculturally appropriate • are useful in natural settings

• can make an immediate and socially significant difference in the child’s communicative skills • help meet the academic and social demands the child faces • help expand communication skills into conversational speech in natural settings • are within the child’s reach as judged by current performance (words, phrases, sentences, conversational speech) Design a Sequence of Treatment that generally moves from: • words to phrases • phrases to controlled (less spontaneous) sentences • controlled sentences to spontaneous conversational speech • treatment in clinical settings to treatment in more naturalistic settings • more structured sessions to progressively less structured sessions • continuous reinforcement to intermittent reinforcement • primary reinforcers to social reinforcers • social reinforcers to natural consequences inherent in communication Prepare stimulus materials for treatment; select at least 20 exemplars to teach each selected target behavior (e.g., 20 phrases that contain the plural s) • select ethnoculturally appropriate, client- and target-specific stimuli that are colorful, attractive, and realistic; prefer objects to pictures • obtain stimuli from the child’s home (the child’s favorite books, toys, and objects) Prepare a Response Recording Sheet on which: • you can write target behaviors • record the occurrence of each behavior Establish Baselines of target behaviors through: 304
Lang. Dis./Comprehensive Treatment • repeated conversational language samples that help reliably document the occurrence of language targets • a set of modeled discrete trials and a set of evoked discrete trials that (a) help capture the production of specific language targets that may not be adequately sampled in conversational speech; (b) are necessary in case of children with no or minimum conversational skills ● Administer Modeled Baseline Trials (note that on baseline trails, there is no reinforcement or corrective feedback for the child’s responses): • place a stimulus picture or object in front of the child or demonstrate an action or enact an event (e.g., a picture of two books) • ask a question to evoke the target response (‘‘Johnny, what do you see?’’) • model the response (‘‘Johnny, say ‘I see two books.’’’) • record the response on a recording sheet (note that there is no reinforcement or corrective feedback) • present the next picture (e.g., that of two cups); repeat the procedure until all the 20 exemplars or 30 or 50 basic words are baserated (basic words to teach a set of core vocabulary for a nonverbal child) ● Administer Evoked Baseline Trials (note that on baseline trails, there is no reinforcement or corrective feedback for the child’s responses): • place a stimulus picture or object in front of the child or demonstrate an action or enact an event • ask a question to evoke the target response; do not model the response • record the response on the recording sheet • repeat the procedure for all the 20 or the total number of selected exemplars 305

in conversational samples and on discrete modeled and evoked trials ● Write a treatment and maintenance plan Word and Phrase Level of Training ● Begin treatment by teaching a set of functional words to a nonverbal or minimally verbal child; select at least 20 functional words, most of them may be among the First Words children acquire (e.g., such words as mommy and daddy; food items like milk, candy, juice, apple, banana; clothing and personal items like socks, shirt, pants, shoe; simple adjectives like big, little; animals like kitty, doggie; and household objects like spoon, chair, book, pen); select child-specific words (e.g., names of siblings and those of pets) after consulting with the parents; establish the target words with the discrete modeled trials: • place a stimulus picture or object in front of the child • ask a question to evoke the target response (e.g., ‘‘Johnny, what is this?’’) • model the response (‘‘Johnny, say sock.’’) • positively reinforce the correctly imitated response; accept an approximation of the correct response • if the child gave a wrong response, give corrective feedback by saying ‘‘No, that is not correct; it is a sock, not a .’’ • if the child did not say anything, just move on to the next trial • move the stimulus picture or item toward you to signal the end of a trial • record the child’s response on the recording sheet (correct, incorrect, or no response)
306
Lang. Dis./Comprehensive Treatment • wait for a few seconds, draw the child’s attention, and present the next trial • when the child correctly imitates the target word on 5 consecutive trials, stop modeling and present evoked trials • follow the same procedure as before: present the stimulus, ask the question (‘‘What is this?’’), but do not model the response • reinforce the correct response and give corrective feedback for the wrong response • if the child gave 3 or 4 wrong responses on the first introduction of evoked trails, reinstate modeling; again withdraw modeling or fade modeling with Partial Modeling when the child correctly imitates the word on 5 consecutive trails • continue training in this manner until the child gives at least 9 correct responses out of 10 evoked (no modeling) trails (a 90% accuracy in producing the word without modeling) • initially reinforce continuously; in gradual steps, reduce the amount of reinforcers by switching to intermittent schedules • always use social reinforcers even when using tangible reinforcers • fade tangible reinforcers if used ● Train 4 to 6 exemplars (words at this level) to a training criterion of 90% correct on a set of 10 trials before you probe ● Note that probes of words taught will involve presenting the same trained words, asking a question, and recording the response; probe trails do not involve modeling, reinforcement, or corrective feedback; just ask questions and record the response ● If the child can produce the words without modeling or reinforcement on at least 4 of the 5 consecutive

presentations, consider those words as tentatively trained ● Train 4 to 6 more (new) words; train the new words as you did the original 4 to 6 words; when they are produced correctly on probe trials (no modeling, no reinforcement, no corrective feedback) ● Continue to train the selected functional words (some 30 to 50); make sure that the words trained include nouns (car, cup, sock, ball, kitty, candy, man, woman, baby), adjectives (big, small, blue, red, thin, thick, smooth, rough, happy, sad, hot, cold ), and main verbs (walking, sleeping, eating, running, jumping, smiling) ● When all of the initially selected words meet the probe criterion, form two-word phrases out of already trained words (e.g., big car, red sock, small kitty; man sleeping, woman walking, doggie eating) ● Begin training the phrases with the same modeled discrete trials; fade modeling and move on to evoked discrete trails ● Probe the phrase production without modeling, reinforcement, or corrective feedback when you have trained 4 to 6 phrases; if probe criterion (90% correct) is met, begin training on new phrases; if not, continue training on the original set of phrases ● When about 20 phrases are trained and have met the probe criterion, shift training to the level of grammatical morpheme and sentence training Teaching Grammatical Morphemes and Syntactic Structures ● Note that one grammatic morpheme, the present progressive ing, may have been taught in the context of main verbs (e.g., walking, eating); similarly, irregular plural words (men, women, children, teeth, feet) also may have been trained as words; note also that some grammatical morphemes can be trained only 308

in sentences (e.g., the auxiliary is; as in The boy is running) others could be trained in phrases (e.g., the regular plural s as in Two books); therefore, phrases and sentences are both involved at this level of training Initially, select grammatical morphemes that can be trained in phrases, as these are syntactically simpler and presumably easier for the child; select the regular plural inflections s (e.g., two books, blue blocks, three cats, green plants) and plural z (e.g., four bags, two dogs, red balls, long trains) for the initial training; other morphemes in phrases include the irregular plurals (two women, big men, white teeth, big feet); prepositions on (on the table, on the bed) and in (e.g., in the hat, in the box); possessive inflection (e.g., mommy’s hat, doggie’s tail) and so forth Use the discrete trial procedure to establish the morphemes; show a picture, ask a question, and model the phrases with an emphasis on the grammatical morpheme (e.g., ‘‘Johnny, What is this? Say two books.’’); fade modeling and train with evoked trails When 4 to 6 exemplars are trained to the training criterion of 90% correct on a set of 10 evoked trials, probe for generalized production of the morpheme; note that at this stage, probes are different than they were at the word level Use initially the Intermixed Probe Procedure in which you alternate trained and untrained exemplars to assess the generalized productions of the morpheme (such as the plural s) in untrained phrase; use at least 10 untrained stimulus items; administer intermixed probes as follows: 1. first, present a stimulus, object, or event used in training; ask a question to evoke the response; reinforce or give corrective feedback; record the response on a Probe Recording Sheet; note that 309

Continue to train the grammatic morphemes in sentences; once again, use the same sequence as the modeled trials leading to evoked trials, intermixed probes, and additional training if the probe criterion is missed When the child meets the probe criterion for morphemes in sentences, move training to conversational speech • evoke speech in naturalistic contexts with pictures, toys, books, and so forth • engage the child in conversation
310
Lang.

When do you eat breakfast?) • negation (e.g., she is not sleeping, he is not eating, they are not walking) ● When a target behavior meets the intermixed probe criterion of 90% correct on at least 10 exemplars taught in sentences, administer the pure probe; note that on a pure probe, you do not present trained exemplars; present only untrained exemplars to evaluate whether a trained grammatic morpheme or a feature is produced in untrained contexts: 1. present a stimulus, object, or event not used in training (e.g., the picture of several elephants, not used in training) 2. ask a question to evoke the response (e.g., ‘‘What do you see?’’) 3. do not reinforce or give corrective feedback for the response; the child’s response may be correct (e.g., ‘‘I see many elephants.’’) or incorrect (e.g., ‘‘I see elephant.’’) 4. record the response as correct or incorrect 5. present another stimulus picture not used in training and follow the same procedure 6. present at least 10 untrained stimulus events 7. calculate the percent correct pure probe response rate ● If the pure probe response rate is less than 90% correct, give additional training using untrained stimulus items ● When a target behavior meets a pure probe criterion of 90% correct on at least 10 untrained exemplars produced in sentences:

Treatment of Language Disorders in African American Children. In treating language disorders of African American children, consider the following guidelines and the African American English characteristics; these characteristics, although different from standard English usage, are not indicative of language disorders; therefore, they are not targets of language treatment; acquiring standard English expressions may be a goal of some African American children and their families; in such cases, teaching standard English patterns of usage is acceptable. ● Make a thorough assessment of the child’s African American English (AAE) and standard English usage; consult the cited sources and the PGASLP ● Make sure that the child and his or her family do use AAE; note that not all African Americans use AAE at home ● Consult with the child’s family members about their goals for language treatment; ask whether they want to have the standard English language patterns taught as well ● Consult with an African American speech-language pathologist in your area or with one who specializes in AAE characteristics; develop resources on AAE and culture for future clinical use ● Select language treatment targets that are consistent with AAE and the goals of the family, are useful to the child, help meet the child’s educational and social demands, and will quickly improve the child’s communicative skills ● Work with the teachers and other special educators to have them appreciate the child’s language patterns and not make negative evaluations ● Refer the child to other specialists as needed (e.g., to an audiologist); educate the family about needed and available services, resources, and support 316

Treatment of Language Disorders in Children of Asian Cultures. Children of Asian cultures are a heterogeneous group; very few generalized statements can be made abut these children; people of Asia speak a bewildering variety of languages, belonging to different languages, and each language may have many dialects; languages of China, the Indian subcontinent, and South East Asia differ widely; much of the available information described under the Asian heading pertains to the languages of China; some of the characteristics listed may apply to other Asian children; use the guidelines offered in this section with caution while treating children of Asian background.

Treatment of Language Disorders in Native American Children. Children of Native Americans (American Indians) also speak a variety of languages belonging to different language families; however, it is likely that many children acquire English as their only language, as the American Indian languages are on the decline even within their own communities; follow the guidelines offered here with caution and try to develop information on the particular language and culture of the child being treated; if the child does speak one of the several Native American languages, he or she is then essentially a bilingual child with varying English proficiency. ● Make a thorough assessment of the child’s primary language and English language skills; consult the cited sources and the PGASLP ● Make sure that the child and his or her family do use a Native American language at home and that English is a second language; many American Indian children do not learn their native language and English may be their only language ● Consult with the child’s family members about their goals for language treatment; ask whether they want to have the standard English language patterns taught as well ● Consult with a speech-language pathologist who knows the child’s Native American language or an 324

• children are taught to listen, observe, and learn thereby • in the judgment of patents, their children may have better auditory comprehension skills than their expressive language skills • some parents may not encourage their children to speak their native language until their articulation is acceptable; therefore, children in the early years may be deprived of language learning opportunities • a long period of nonverbal communication (pointing and gesturing) may pass before children begin to use words • talking too much or talking English may be viewed as imitating the White Man • Native American etiquette requires that a speaker pause before answering a question; quick answers imply that the question did not require much thought • if unsure of an answer, children may not respond to a question • children may be reluctant to express their opinions until the adults indicate that they have earned their right express their own opinions • public expression of strong feelings is generally discouraged • expression of grief in the presence of outsiders may be acceptable only during official mourning ceremonies Roseberry-McKibbin, C.

Treatment of Language Disorders: Specific Techniques or Programs. Several specific treatment programs are available; some are more comprehensive than others; some have better evidence than others; some 326
Lang. Dis./Treatment: Specific Programs have little or no evidence; clinicians need to check the evidence before selecting a technique. Activity-Based Language Intervention. Treating language disorders with the help of various activities designed to promote language production; a classroombased approach in which each child has an individualized educational plan; activities are part of classroom activities and use natural antecedents and consequences. ● Plan activities that promote the production of specific language structures in children ● Plan activities around a theme if appropriate (e.g., activities related to going on a camping trip) ● Read stories, narrate events, and sing songs about the theme; include the various language targets for the children in the class ● Ask questions about the presented information ● Forget to give needed objects during activities, leading the child to request them ● Give needed items one at a time so the child requests each one ● Put needed things out of reach so the child asks for them ● Put needed things in a clear jar that the child can see but cannot open to gain access and hence has to request help ● Hide the child’s belongings to encourage requests ● Introduce novel items (e.g., wear a funny hat) and let those who talk about it wear it ● Pause during verbal or nonverbal actions so the child will request that you continue Bricker, D., & Cripe, J. (1992). An activity-based approach to early intervention. Baltimore, MD: Paul H. Brookes.
Child-Centered Approaches to Language Intervention. Play-oriented, Indirect Language Stimulation in which the clinician does not target specific language structures to teach; the clinician may arrange stimuli 327
L
Lang. Dis./Treatment: Specific Programs that are more likely to evoke language structures; uses such techniques as Reversed Imitation (clinician’s imitation of the child’s utterance), Expansion, Extension, Parallel-Talk, Recast, and Self-Talk (all described later in this section); needs more evidence to document its effectiveness. Conversational Repair. Skills of handling breakdown in communication; a pragmatic language structure and a treatment target during conversational skill training; refers to such skills as asking questions when messages are not clear and responding to requests for clarification; needs more evidence to support its widespread use.
Teach the Child to Request Clarifications From a Speaker. Play the role of a speaker who makes ambig-
L
uous or unclear statements:
● Make ambiguous statements (e.g., say ‘‘Give me the
car’’ when you have displayed several toy cars)
● Wait for the child to request clarification ● If the child does not request clarification and responds
anyway (such as picking one of the cars), say ‘‘No’’
● Wait for the child to request clarification ● If the child does not request clarification, model a re-
● ● ● ● ● ● ●
sponse for the child (e.g., ‘‘When you are not sure, I want you to ask me ‘What do you mean?’ OK?’’) Make another ambiguous statement Immediately model the request for clarification for the child Reinforce the child for imitating the request for clarification (e.g., ‘‘What do you mean?’’) Make another ambiguous statement Prompt (not model) a request for clarification (e.g., ‘‘What do you ask me?’’) Reinforce the child for asking for clarification (e.g., ‘‘What do you mean?’’) Introduce varied ambiguous statements
328
Lang. Dis./Treatment: Specific Programs ● Fade modeling and prompting ● Train parents in teaching the child to request for
clarification
● Probe the generalized repair skill by presenting untrained
messages
● Continue training until a set probe criterion (such as
90% accuracy in responding with the target skill) is met
Teach the Child to Vary the Expressions When Requested by a Listener Who Does Not Understand. Play the role of a listener who does not fully understand the expressions of the child: Ask the child to repeat Ask the child ‘‘What do you mean?’’ Tell the child ‘‘I do not understand’’ Negate a child’s utterance so the child will clarify by assertion (‘‘You did not go on the roller coaster 20 times did you?’’; the child might say ‘‘No, I went on it two times.’’) ● Model the clarified statement by modifying what the child said (‘‘You mean you went on the roller coaster two times, right?’’) ● Rephrase the child’s utterance into a question and say it with a rising intonation (‘‘You went on the roller coaster 20 times?’’) ● Model different ways of saying the same thing ● Ask the child to say it differently; reinforce varied phrases or sentences ● Periodically stop responding (e.g., to the child’s request) to prompt the child to rephrase ● Train parents to prompt the child to vary expressions and to reinforce the child for compliance ● Probe the generalized repair skill by presenting untrained messages ● Continue training until a set probe criterion (such as 90% accuracy in responding with the target skill) is met ● ● ● ●

Conversational Skill. A language skill in maintaining a dialogue with one or more partners; an intervention goal for all clients with language disorders; collection of skills that include Topic Initiation, Topic Maintenance, and Turn Taking (all described later in this section). ● Use Peer Modeling (described later in this section); recruit peers who have good conversational skills to model those skills to the client ● Train the peers to model and have the client participate in conversation ● Closely monitor the behaviors of the peer models and the client ● Train peer models to be the hosts of a mock talk show ● Ask open-ended questions (you or the peer model) ● Ask follow-up questions (you or the peer model) ● Prompt the peer and the client for appropriate behaviors ● Train the client to ask questions ● Reinforce the client for new topic initiations, appropriate turn taking, and topic maintenance; if necessary, train these skills separately ● Show videotaped model interactions between adults, between children, and between children and adults ● Let the children analyze the tapes ● Let the children recreate what they saw on the tapes ● Train parents to conduct informal conversational skills training sessions at home Delayed Stimulus Presentation. A child language intervention procedure in which the clinician delays providing such special stimuli as modeling for about 15 seconds to see if the child responds without such stimuli; provides the stimuli only when the child does not respond within the time limit.
330
Lang. Dis./Treatment: Specific Programs ● Establish joint attention regarding a stimulus (e.g.,
hold an object; establish eye contact with the child; look questioningly or expectantly) ● Do not speak for 15 seconds when the child approaches you or looks at you ● Model a mand or a name after the 15-second delay ● Give the object when the child imitates your modeling ● Give the object anyway when you have modeled 3 times and the child has not yet imitated Direct Language Treatment Approaches. Intervention approaches in which the clinician selects specific language targets, designs a treatment environment and implements the treatment; uses specific stimuli including modeling, prompting, and manual guidance; uses explicit reinforcement contingencies; expects the child to imitate or produce specific targets upon stimulation; moves through a planned sequence of treatment stages. Environmental Language Intervention Strategy (ELIS). A language intervention method for preschool children; developed and researched by J. D. McDonald and associates; a structured, direct treatment strategy; takes a semantic approach to teaching grammar; emphasizes generalized production at home; especially useful in training parents to conduct language stimulation sessions at home. ● Establish baselines of selected target language structures ● Structure treatment in three phases: imitation, conversation, and play ● Introduce the three procedures in the first three individual training sessions ● Train parents to record responses and administer the treatment program at home; train them in the Management of Behavioral Contingencies
331

Lang. Dis./Treatment: Specific Programs ● After the first three training sessions, integrate imi-
tation, conversation, and play into a single session
● Spend the first 15 minutes on imitative productions

• present a nonlinguistic stimuli (throw a ball) • present a linguistic stimuli (e.g., ‘‘Say, throw ball.’’) Spend the next 15 minutes on conversational speech • present the same nonlinguistic stimuli • ask a question (e.g., ‘‘What am I doing?’’) • model if necessary (e.g., ‘‘Say throw ball. What am I doing?’’) Spend the final 15 minutes on play activity during which the production of the target behavior is reinforced • let the child play with the material used in imitation and conversation • evoke responses from the child that are relevant to the child’s actions (e.g., if the child throws the ball, ask, ‘‘What are you doing?’’) Give such positive reinforcers as tokens and verbal praise for correct responses Give such corrective feedback as Time-Out for incorrect productions Ask parents to conduct at home three weekly sessions similar to yours In each session, review the records of home training and suggest modifications

Event Structures in Language Treatment. Use of repetitive, sequentially organized, familiar events from daily life to teach language structures to children; an event structure may be the same as a Script used in Script Therapy (described later in this section); the two may be used in conjunction; also similar to Joint Ac332
Lang. Dis./Treatment: Specific Programs tion Routines or Interactions (described later in this section); needs more evidence to support its practice. ● Select a common event the child has repeatedly experienced (e.g., shopping for a toy, eating in a restaurant, taking part in a birthday party) ● Describe the event verbally ● Assign roles to yourself and the child (e.g., customer and the store clerk) ● Use props to act out the event ● Reverse roles and act out the events; repeat until the various language structures of interest are rehearsed ● Evoke words and phrases as you act out the event by using pauses at junctures (using the Cloze Procedure) ● Evoke increasingly complex or longer description of events ● Vary the sequence and event elements (e.g., after having worked with the event shopping for a toy, have the child work with the event shopping for clothing) ● Violate expected events or sequences and let the child question you or correct you (e.g., go to the sales clerk without trying the clothes) Expansions. Expanding a child’s incomplete or telegraphic statements into grammatically more complete productions; part of Indirect Language Stimulation. ● Arrange a play situation that provides opportunities for language production ● Engage in parallel play with the child or take part in the child’s activities ● Expand the child’s structurally incomplete productions into more complete sentences (e.g., a boy says ‘‘baby cry’’ as he looks at a picture; you expand it into ‘‘The baby is crying.’’) ● Do not ask the child to imitate your expansions Expatiations. The same as Extensions. 333
L
Lang. Dis./Treatment: Specific Programs
L
Extensions. Comments on the child’s utterances to add additional meaning; part of Indirect Language Stimulation; also known as Expatiations. ● Arrange a play situation that provides opportunities for language production ● Engage in parallel play with the child or take part in the child’s activities ● Extend the child’s semantically limited productions into semantically richer, structurally complete sentences through comments, (e.g., a girl says ‘‘play ball’’ as she plays with a ball; you extend it to include additional meaning: ‘‘Yes, you are playing with a big ball’’; ‘‘You are playing with a blue ball.’’) ● Do not ask the child to imitate your extensions Eye Contact. A potential pragmatic communication target behavior for certain children who do not look at the listener while speaking or at the speaker while talking; potentially culturally determined; need culturally sensitive assessment and treatment. ● Target eye contact from the beginning and especially during conversational speech training ● Use simple instruction and verbal praise ● Prompt the child by saying ‘‘Look at me’’ before you present stimuli, when you begin to talk, and when the child begins to talk ● Hold the stimulus parallel to your face so the child looks at the face and the stimulus simultaneously ● Praise the child for maintaining eye contact ● To track progress, measure the duration for which eye contact was maintained at the beginning (baseline) and throughout the treatment phase ● Fade the prompts or other cues used Focused Stimulation. A technique of language intervention in which the clinician repeatedly models a target structure to stimulate the child to use that structure; usually a part of play activity. 334
Lang. Dis./Treatment: Specific Programs ● Design a play activity to focus on a particular lan-
guage structure (e.g., the plural morpheme s)
● Collect various stimulus materials (books, cups, hats) ● Talk about the materials and repeatedly model the
plural constructions (e.g., ‘‘I see two books here. The books have pictures. Here are two red cups. You can drink out of these cups. There are some hats. The hats are big.’’) ● Do not correct the child’s wrong productions ● Respond to the child’s nontarget responses without insisting on the correct response (e.g., the child says ‘‘The book is nice’’; the clinician says ‘‘Yes, the books are nice.’’) ● Continue until the child begins to produce the target structure Imitation of Child’s Utterances. Reversed Imitation in which the clinician imitates a child’s utterance during Indirect Language Stimulation; need more controlled clinical data to support its use. Incidental Teaching Method. A Naturalistic Child Language Teaching Method (described later in this section) that uses typical, everyday verbal interactions to teach functional communication skills; the child often initiates an interactional episode; the clinician turns such episodes into opportunities to teach language; emphasis is on communication; effective when the child and the teacher interact for extended periods of time and in natural settings (e.g., in special education classrooms, institutions for the retarded and the autistic); excellent method for parents to learn and use at home) ● Select certain functional communicative skills for teaching (e.g., requests) ● Arrange therapy situations such that the child is likely to initiate a conversational exchange (e.g., place attractive toys on a shelf the child can see but 335

cannot reach; arrange a child’s clothing items or some desirable food items) Stay close to the arranged materials and give nonverbal cues to speak (focused attention on the child and a questioning look) Give a verbal cue (e.g., ask ‘‘What do you want?’’) only if the nonverbal prompts fail to evoke a response from the child Give cues that evoke more complex responses (e.g., ‘‘Ask me in a sentence’’ if the child gives only singleword responses) Reinforce the child with natural consequences (e.g., ‘‘Good, here is the car’’; ‘‘Very good, here is your sock’’; ‘‘Fine, have some juice.’’ ) Arrange as many such teaching episodes as possible in a day

Indirect Language Stimulation. A collection of language stimulation procedures that are a part of playoriented approach to teaching language disorders; also called Child-Centered Approach (described earlier in this section); less structured and more naturalistic; thought to be especially suitable for children who are passive, reluctant, or unmotivated to communicate; based on the assumption that variables observed in normally developing children are effective clinical treatment strategies; needs more controlled evidence to support this approach. ● Arrange a play situation that provides opportunities for language production ● Choose the play materials that are relevant for the targeted response ● Let the child lead the interaction ● Engage in parallel play with the child or take part in the child’s activities 336
Lang. Dis./Treatment: Specific Programs ● Talk about what the child is doing, looking, playing,
or talking
● Describe what you do (e.g., ‘‘See, I am drawing a
face; I am drawing’’; Self-Talk) (described later in this section) ● Describe or comment on what the child is doing (Parallel-Talk, described later in this section) (e.g., you say ‘‘You are drawing; you are drawing a face; you are making a nose.’’) ● Imitate the child’s production (do not ask the child to imitate) ● Use Expansions (described earlier in this section); expand the child’s telegraphic speech into grammatically more complete sentences (e.g., the child says ‘‘Mommy hat’’; you expand this to ‘‘That is Mommy’s hat.’’) ● Use Extensions (described earlier in this section); comment on the child’s utterances to add additional meaning (e.g., the child says ‘‘Mommy hat,’’ and you say ‘‘Yes, it is a big blue hat.’’) ● Recast (described later in this section) the child’s utterances (expand the child’s utterance type into a different kind of sentence (e.g., the child says ‘‘Mommy hat’’; you ask a question, ‘‘Is this Mommy’s hat?’’ or make a statement ‘‘This is not Mommy’s hat.’’) ● Do not ask the child to imitate; do not target specific language structures; do not explicitly reinforce correct productions Integrated Functional Intervention. Approach to language treatment that emphasizes natural contexts for training, conversational speech as the main mode of training, and increased involvement of parents and significant others in promoting and maintaining language skills. Interactive Language Development Teaching. One of Directed Language Treatment Approaches to teach 337
L
Lang. Dis./Treatment: Specific Programs syntactic structures; the clinician reads a story to the child and then asks a series of questions designed to evoke specific language structures from the child. ● Select a story that targets language concepts (e.g., camping, cooking) and specific language responses (e.g., the auxiliary is or preposition on) ● Read the story to the child ● Ask questions frequently as you tell the story to evoke specific responses (e.g., ‘‘Daddy said a bear is coming [part of the story]. What did Daddy say?’’ [question to evoke the response ‘‘bear is coming’’]) Lee, L., Koeningsknecht, R., & Mulhens, S. (1975). Interactive language development teaching. Evanston, IL: Northwestern University Press.
L
Joint Action Routines or Interactions. Use of repetitive, routinized activities in early language stimulation; an Indirect Language Stimulation method; similar to Script Therapy (described later in this section) or may be a variation of it. ● Use such established routines as ‘‘peek-a-boo’’ ● Design your own routines of action (e.g., always start treatment with telling the same short story that contains certain target language structures) ● Encourage the child to use the repetitive words, phrases, and sentences ● Reverse roles and let the child practice other language structures ● Violate a routine and let the child question you (e.g., skip the story and let the child ask ‘‘Story?’’ or ‘‘What about the story?’’) Joint Book Reading. Systematic use of storybook reading to teach or stimulate language in children; allows for repetitive use and practice of the same phrases and concepts; helpful in establishing joint attention as well. 338
Lang. Dis./Treatment: Specific Programs ● Select story books that are linguistically and cultur-
ally appropriate for children under treatment
● Select books with colorful pictures ● Read the same story several times during a few ses-
sions so that children memorize it
● Use prosodic features frequently to draw attention
to specific language structures
● When the children know the story well, pause at
●

points containing target language structures and prompt the children to supply the words, phrases, or sentences During different readings, pause at different junctures so the children produce different language structures Manipulate and vary pause locations that prompt progressively longer utterances from the children Ask a child to ‘‘read’’ (recite from memory, but looking at the text and the pictures) and pause Let the other children supply the words, phrases, and sentence

Matching-to-Sample. A language teaching strategy; a child’s response is reinforced only if it matches a sample; helps generate rule-based responding based on physical or functional similarity; supported by some evidence. Teaching Matching-to-Sample on the Basis of Physical Similarity ● Display an array of stimuli in front of the child (e.g., a book, a ball, and a pencil) ● Hold a sample and show it to the child (e.g., a different book than the one displayed in front of the child) ● Ask the child to match it to the one displayed ● Reinforce the correct matching (e.g., pointing to the book) Teaching Matching-to-Sample on the Basis of Functional Similarity ● Display an array of stimuli in front of the child (e.g., a large blue sneaker, a small brown ball) ● Hold a sample that matches the function of one of the objects but the physical property of the 340
Lang. Dis./Treatment: Specific Programs other object displayed (e.g., a small brown shoe) and show it to the child ● Ask the child to match it to the one displayed ● Reinforce the correct matching (e.g., the blue sneaker) Milieu Teaching. A collection of child language intervention procedures that emphasize natural, functional, conversational communicative contexts for teaching language; a naturalistic child language teaching method; uses natural consequences as reinforcers; includes the Mand-Model and Incidental Teaching Method (described earlier in this section); supported by controlled evidence. Narrative Skills Training. A speaker’s description of events (stories, episodes) and experiences in a logically consistent, cohesive, temporally sequenced manner; analyzed in terms of a Story Grammar (described later in this section); an advanced language skill targeted during the final stages of intervention. ● Use the Event Structure (described earlier in this section) approach to give children experience in establishing Scripts (schemes of events) • play such scripts as grocery shopping, eating in a restaurant, birthday parties, camping trips, vacations, playing certain games, and so forth • play daily routine scripts (get children involved in daily activities) • repeatedly read or tell the same stories so the children memorize the words, temporal sequences, characters, and events • let the children act out the stories • let the children switch the roles on repeated scripts ● Ask children to narrate experiences as they play out scripts and assume different roles ● As you retell stories, pause before important phrases or critical descriptions so the children supply them 341

Lang. Dis./Treatment: Specific Programs ● Prompt the phrases and descriptions as the children
hesitate; fade the prompts
● Ask the children to tell the stories or narrate events
without enacting the scripts but with the help of pictures or slides ● Ask the children to tell stories or narrate events without scripts, pictures, or slides ● Ask the children to narrate new events or experiences (not rehearsed or scripted)

Naturalistic Child Language Teaching Method. An approach that emphasizes natural, functional, conversational communicative contexts for teaching language to children; uses loose training structure; uses natural consequences as reinforcers; includes Incidental Teaching Method, Joint Action Routines or Interactions, Mand-Model, and Script Therapy (all described in this section). Parallel-Talk. Describing or commenting on what the child is doing during play activities; part of Indirect Language Stimulation. ● Arrange play activities designed to enhance opportunities for language production ● Play with the child ● Describe the child’s actions (e.g., ‘‘You are playing with the ball; you are bouncing the ball.’’) Peer Modeling. A child language intervention method in which the peers are trained to model the target skills for the child. ● Select a peer who agrees to help and is acceptable to the client 342
Lang. Dis./Treatment: Specific Programs ● Have the peer observe your treatment sessions ● Describe the target behaviors, modeling and imita-
tion sequence, and reinforcement procedures
● Let the peer model and reinforce the child’s produc-
tions in your presence
● Refine the peer’s skills in modeling the target
behaviors
● Ask the peer to submit recorded language samples
that document appropriate modeling outside the clinic ● Periodically assess the results of peer modeling and provide additional training to the peer Reauditorization. Clinician’s repetition of what a child says during language stimulation; often combined with such other techniques as modeling (often without requiring imitation); need more evidence to show its usefulness or effectiveness. ● Repeatedly model a target language feature in varied linguistic contexts (e.g., you say ‘‘The book is on the table; the cat is on the tree; the dog is on the house.’’) ● Point to a target stimulus or ask a question (point to a bird on a tree; or ask ‘‘Where is the bird?’’) ● Repeat the child’s production ‘‘in tree’’ or ‘‘bird is in the tree’’ Recast. Expansion of a child’s utterance type (sometimes presumed) into a different type of sentence; a method of play-oriented, unstructured, Indirect Language Stimulation. ● Arrange play activity designed to enhance opportunities for language production ● Play with the child ● Expand the child’s utterance into a sentence type that may be different from the child’s presumably intended sentence type (e.g., the child says ‘‘Big ball’’; you expand it into a negative sentence, ‘‘No, 343
L
Lang. Dis./Treatment: Specific Programs
L
it is not a big ball’’; or expand it into a question form, ‘‘Is this a big ball?’’) ● Do not ask the child to imitate your recast sentences Request for Repair. A listener’s (clinician’s in intervention sessions) use of various devices to let the client know that his or her expression was not clear and that the message needs to be altered. ● Ask the speaker (the child) to repeat ● Ask a question (‘‘What do you mean?’’) ● Use negation to prompt the child to clarify a statement (‘‘You did not have seventy friends at your birthday party, did you?’’) ● Model the correct response by saying what the child meant (‘‘You mean you had seven friends at your birthday party.’’) ● Turn a child’s utterance into a question with a rising intonation (‘‘You had seventy friends?’’) Scaffolding. A collection of procedures to make it easier for a child to produce specific language behaviors or perform academic tasks; communicative assistance or support given to the child by peers and adults; a shared learning environment that promotes communication between the child and adults; ways to simplify communicative and academic tasks for the child; needs experimental support. To Teach Language Use ● Support the child in his or her attempts to speak ● Direct the child’s attention to important aspects of learning and communication ● Give feedback to the child’s questions and comments ● Give semantically contingent feedback ● Provide prompts and models ● Let peers help the child ● Encourage the child to ask questions ● Let the child take part in problem-solving activities
344
Lang. Dis./Treatment: Specific Programs ● Expand and elaborate the child’s utterances ● Fade the degree of support
To Promote Academic Learning in a Collaborative Model ● Ask the teacher to reduce academic demands that the child cannot meet or give more time for assignments ● Highlight important terms, issues, questions, definitions in a child’s textbook; ask the child to find the meanings of terms in a dictionary ● Work on listening, reading, writing, and other skills that are required in the classroom Kirchner, D.

Script Therapy. Language intervention procedure in which events and routines known to the child or made familiar by the clinician (Scripts) are used; procedures are similar to those under Event Structures and Joint Action Routines or Interactions (described earlier in this section); used in teaching advanced language skills including narrative skills; a script is usually not a written document although it may be in treatment; refers mostly to presumed ideas or a mental scheme a child may have about such common experiences as eating in a restaurant or grocery shopping; needs experimental support. ● Select language targets appropriate for the children to be taught (e.g., such action-object-locative constructions as ‘‘Put the doll in the box’’) ● Select routinized scripts for each target (e.g., scattered toys that the mother and the child sort and put away before bedtime)

to yourself (e.g., one plays the role of the mother of a child being taught) Scatter several toys and have a box, a shelf, a table, and other objects for storing the toys Begin by saying something to initiate the script (routine activity) (e.g., ‘‘OK, it is bedtime! Let us pick up these toys and put them away.’’) Model target responses (‘‘I am putting the doll in the box’’) and if the child imitates, reinforce Ask questions (e.g., ‘‘What are you doing?’’) and reinforce correct responses (‘‘I am putting the car on the shelf.’’) Complete the script and reenact the same or similar scripts Probe for generalized production (probe the same target responses with different scripts)

Self-Talk. Clinician’s description of her own activity as she plays with the child; a method of play-oriented, more or less structured, Indirect Language Stimulation. ● Arrange play activities designed to enhance opportunities for language production ● Play with the child ● Describe your own actions using language structures appropriate for the child (e.g., ‘‘I’m squeezing the rubber ducky here; see I’m squeezing.’’) Story Grammar. The structure of narratives that may be treatment targets for children with language disorders; a story grammar includes the following elements:
346
Lang. Dis./Treatment: Specific Programs ● Setting statements (e.g., introduction to the story,
● ● ● ● ● ●
the characters, the physical setting, the temporal context) Initiating events (e.g., episodes that begin a story) Internal response (e.g., the characters’ emotions, reactions, thoughts) Internal plans (e.g., the characters’ strategies for achieving their objectives) Attempts (e.g., actions the characters take to achieve their objectives) Direct consequences (e.g., results of actions) Reactions (e.g., the characters’ response to the results)

Topic Initiation (Treatment for). The skill to start conversation with a new topic; a conversational skill; a pragmatic feature of language; a language treatment target; children with language disorders either fail to initiate topics or introduce inappropriate topics. ● Arrange a variety of stimuli that could trigger a new topic: objects, pictures, storybooks, topic cards (for children who can read), toys, structured play situations such as a kitchen and so forth ● Introduce one of the stimulus items or situations and draw the child’s attention to it (e.g., a picture of a family setting up a tent in a park) ● Wait for the child to initiate conversation about the picture and the story ● If the child does not initiate a topic, instruct the child to say something about the picture ● If the child does not initiate, prompt by beginning the story (‘‘They are setting up a. . . .’’)
347
L
Lang. Dis./Treatment: Specific Programs ● Lavishly praise the child for saying anything related
to the topic depicted
● Accept statements that are remotely connected to
L
the topic at hand; gradually, demand more relevant responses ● Do not interrupt the child or overly correct the forms of responses ● Ask the child to use the topic cards to initiate new topics ● Ask the child to think of new topics to talk about ● Prompt new topics ● Withdraw or fade such prompts, cues, cards, pictures and other special stimuli to make topic initiation more spontaneous ● Train parents to use your techniques so they can continue intervention at home Topic Maintenance (Treatment for). A pragmatic language skill and treatment target; talking about a single general topic for extended duration; frequent and abrupt switching of conversational topics suggests lack of this skill. ● Target topic maintenance when training has moved to the conversational speech stage or sooner if the session structures allow it ● Let the child select topics of interest for talking ● Set a realistic duration for which you want the child to talk on a single topic; or set a target number of words to be produced on a topic ● Increase the duration or the number of target words in gradual steps ● Use such devices as Tell me more. What about that? What happened next? Who said what? Where was it? When did that happen? and so forth to stimulate more speech on the same topic ● Reinforce the child for maintaining the topic
348
Lang. Dis./Treatment: Specific Programs ● Stop the child when he or she abruptly switches the
topic
● Move the child back to the target topic ● Train on a few topics and then probe with untrained
topics to see if the skills have generalized
● Train on additional topic exemplars if the skills have
not generalized Turn Taking (Treatment for). Appropriate exchange of speaker and listener roles during conversation; a pragmatic language skill; an advanced treatment target; interrupting a speaker and not responding to cues to talk are indicators of deficient turn taking. ● Select turn taking as a target when treatment has advanced to conversational speech or sooner if the child can handle it ● Baserate the number of interruptions and failure to take cues to talk ● Design a signal for the child to talk (e.g., such verbal cues as ‘‘Your turn’’ or nonverbal cues as a hand gesture to suggest you speak) ● Design a signal that says do not interrupt or do not talk because it is your (clinician’s) turn to talk (e.g., finger on your lips) ● Use such other discriminative stimuli as a real or toy microphone that you exchange with the child; the one holding the microphone talks and the other listens ● Reinforce the child for talking only when signaled or while holding the microphone ● Follow the same rule that you impose on the child (e.g., talk only when you hold the microphone) ● Teach the child to say ‘‘It is your turn’’ ● Reinforce the child for yielding the floor ● Teach turn taking until the child meets a performance criterion (e.g., no errors of turn taking in two consecutive conversational exchanges)
349

L
curacy in turn taking while not receiving reinforcers) Whole Language Approach. A philosophical approach to language, especially reading and writing, that has implications for oral language teaching; does not strictly refer to a method of teaching oral language; advocates that in teaching, language should not be broken down into components; believes that all aspects of literacy including reading, writing, listening, and talking should be simultaneously taught as an integrated whole; considers the Language-Based Classroom Model of intervention to be the best to teach language because all aspects of literacy can be effectively addressed; suggests that academic programs should be the basis of language teaching; advocates a naturalistic approach to language teaching; the approach has not been supported by efficacy research and many educational specialists now reject this approach; its use in teaching language to children with language disorders is questionable; there are better, experimentally supported alternatives. Language Deviance in Children. Somewhat similar to the term Language Disorders in Children; includes a connotation of some abnormality in the acquisition or use of language for which there is little empirical support; not strictly a synonym for language disorders; treatment procedures the same as those for Language Disorders in Children. Language Impairment. Generally the same as language disorders; includes an acceptable connotation of a disturbed function; may be used interchangeably with language disorder; treatment procedures the same as those for Language Disorders in Children. 350
Language-Learning Disorders Language-Learning Disorders. Generally the same as language disorders; links language disorder to a general learning disorder that negatively affects academic learning; often used in special educational contexts; treatment procedures the same as those for Language Disorders in Children.
Language Problems. Generally the same as language disorders; a more general term that may be used interchangeably with language disorders; treatment procedures the same as those for Language Disorders in Children.
Language Stimulation by Parents.
Activities parents implement at home to stimulate language in infants and toddlers; may be the only recommendation for a child; may supplement or parallel clinicians’ treatment; supported by some evidence; more needed ● Assess the child and his or her family ● Assess the parents’ education, sophistication, time commitment, and motivation to conduct regular activities at home ● Design a language stimulation program for the child ● Test the program in the clinic for a few sessions to make sure it works ● Have parents observe your sessions ● Train parents in the effective methods; model the methods frequently ● Have parents conduct a session or two in the clinic ● Give feedback and refine their skills ● Train them to keep records of therapy that you can evaluate ● Give parents simple, clear written instructions ● Give parents video taped samples of treatment techniques ● Periodically assess the child and the parents’ sessions at home ● Suggest needed modifications and movement to higher levels of training ● Initiate formal treatment when your assessment indicates a need for it 351
L
Laryngeal Cleft Laryngeal Cleft.
A cleft between the larynx (cricoid cartilage) and the esophagus; caused by a failure of dorsal fusion of the cricoid lamina; may be accompanied by other congenital anomalies, including feeding and respiratory problems soon after birth. ● Treatment is surgical closure of the cleft
Laryngeal Cysts. Formation of small, fluid-filled sacs on the larynx, especially in the ventricle; often congenital; caused by accumulation of glandular secretion in submucosal; symptoms include swollen false (ventricular) folds; if enlarged, can result in hoarseness. ● Treatment is surgical removal of the cyst ● Follow-up voice therapy may be needed in some cases
L
Laryngeal Hyperkeratosis. A thickening of the laryngeal mucosa resulting from an abnormal growth of the epithelium; causes may include cigarette smoking, heavy alcohol use, environmental pollutants, dust, noxious gases, and strained and tense speaking habits; usually occurs on the true vocal folds; may sometimes be premalignant. ● Modify the client behavior to reduce exposure to the listed causal factors
Laryngeal Leukoplakia. Appearance of white patches on the laryngeal mucosa; voice may be hoarse; may be premalignant. ● Modify client behavior to reduce or eliminate smoking ● Do not offer voice therapy for hoarseness as it is not effective
Laryngeal Stoma. An opening made into the trachea between the thyroid glands to allow for breathing in patients with laryngectomy.
Laryngeal Web. Growth of a thin membrane across portions of the vocal folds; may be congenital or induced by trauma later in life; negatively affects respiration. ● Treatment is surgical removal of the web 352
Laryngectomee Laryngectomee.
A person who has had a partial or total
Laryngectomy.
Laryngectomy. Surgical removal of all or part of the larynx because of disease or trauma.
Treatment Procedures, Laryngectomy Preoperative Evaluation and Counseling ● Work as a member of the rehabilitation team ● In consultation with the surgeon, counsel the patient and the family about the effects of medical treatment on communication ● Invite and answer all questions from the patient and the family members; give answers that are consistent with advice from other professionals on the team ● Do not withhold information if the patient would like to hear it ● Obtain a sample of the patient’s speech and writing; make an assessment of client’s communication skills ● Describe various methods of speaking without a larynx; discuss communication options that may be preferable to the client; be consistent with the surgeon’s preferences and recommendations ● Reassure the patient that he or she will talk again by using new techniques ● Have the patient meet and speak with a rehabilitated Laryngectomee who has mastered Alaryngeal Speech Postoperative Management ● If no prior counseling, discuss the current condition of the patient and the prospects for new methods of communication ● Review the information provided during the preoperative counseling ● Discuss methods of Alaryngeal Speech (described later in this section) ● Demonstrate how electronic speech aids work 353
L
Laryngectomy ● Teach the patient to use a Pneumatic Device for Alar-
yngeal Speech (described later in this section), if appropriate, to support immediate communication ● Discuss the patient’s rehabilitation plan; be cautious in making prognostic statements ● Give written information on rehabilitation plans and possibilities for the patient to read later ● Arrange a visit from a rehabilitated Laryngectomee to encourage the patient
Teaching New Methods of Communication
L
General Principles ● Select an appropriate method of communication that the client prefers, judged to be efficient, and is practical ● Teach the client to use the new method of communication ● Select either a Pneumatic Device for Alaryngeal Speech or an Electronic Device for Alaryngeal Speech (both described later in this section) for permanent communication ● Let the client use a pneumatic device during the early postsurgical period as it is easier to use within days after surgery; let the client switch to an electronic device if that is preferred ● Begin to teach the use of an electronic device only after the neck and throat areas recover from swelling and tenderness and the surgical suture lines heal ● Teach tracheoesophageal speech if the patient is surgically prepared for it ● Consider both individual and group therapy sessions ● Determine the frequency of treatment sessions based on the patient’s physical condition ● Consider daily sessions in the beginning if the patient’s physical stamina permits them ● Hold at least one weekly session ● Get family members involved in training sessions
354
Laryngectomy ● Let the patient’s performance and progress dictate the
pace of therapy
● Ask the client to practice the new method of commu-
nication at home Teach Alaryngeal Speech With Electronic Devices ● Select a neck-held electronic larynx after discussing various models with the patient ● Demonstrate first what the instrument sounds like and then how speech produced with its help sounds like ● Experiment with the best position on the neck (usually under the jaw); let the head of the device a good contact with the skin without pressing it ● Manipulate the button for sound production and ask the patient to count aloud ● Ask the patient to clearly shape the words with the mouth ● Ask the patient not to exhale forcefully ● Teach the patient to handle the device ● Instruct the patient to coordinate sound and speech and to turn off the sound when not talking ● Reduce the patient’s rate of speech to increase intelligibility ● Teach the patient to increase articulatory precision by practicing words that begin with voiceless consonants ● Shape progressively longer utterances ● Teach the client to maintain eye contact with the listener Teach Alaryngeal Speech With Pneumatic Devices ● Use pneumatic devices during the early phase of rehabilitation ● Select a pneumatic device after discussing various options ● Teach the patient to place the cup end of the device firmly over the Laryngeal Stoma so that there is no air leak
355
L
Laryngectomy ● Ask the patient to hold the cup end over the stoma and
produce a sound by blowing out
● Ask the patient to blow out two and three sounds for
every breath
● Ask the patient to change the pitch by increasing the
air pressure
● Ask the patient to place the mouth piece on top of the
L
tongue, while keeping the cup end over the Laryngeal Stoma ● Ask the patient to say vowels and then words ● Shape progressively longer utterances ● Give appropriate positive and corrective feedback Teach Esophageal Speech ● Begin esophageal speech training soon after patient starts eating food orally ● Describe the anatomy and the physiology of esophageal speech production ● Describe esophageal sound production to the patient ● Use diagrams to explain esophageal speech ● Teach the client the production of esophageal sound ● Try various procedures and settle on the one most effective with the client ● Teach the patient to use the injection method of taking air into the esophagus • ask the patient to press the tongue tip against the alveolar ridge to push the air back toward esophagus without the tongue making contact with the pharyngeal wall (glossal press) • ask the client to press the tongue tip against the alveolar ridge and to move the tongue back to make contact with the pharyngeal wall; thus push air back into the esophagus (glossopharyngeal press) • ask the patient to keep the velopharyngeal port closed • ask the client to inject the air in an audible manner, producing the sound called the ‘‘klunk’’ 356
Laryngectomy ● Teach the patient to use the inhalation method of tak-
ing air into the esophagus if necessary; be aware that some experts use only the injection method for most of their patients • teach the patient to synchronize the air intake through the stoma with air intake through the mouth into the upper esophagus; relaxed PE segment and the resulting negative pressure there will help air movement into upper esophagus ● Ask the patient to produce plosive consonants to stimulate esophageal sound ● Instruct the patient to say ta-ta-ta ● Ask the patient to use easy injection of air and say a series of ta-ta-ta ● Reinforce a likely emergence of esophageal sound ● Teach the patient to puff the cheeks out and move the air trapped in the mouth from one side to another; instruct the patient to move this trapped air quickly into the esophagus ● Ask the patient to produce words that typically trigger sound production: church, stop, skate, scotch, and scratch ● Use single phonemes initially ● Move on to single syllable words ● Increase response complexity ● Ask the patient to slow down the rate of speech Teach Tracheoesophageal Speech ● Select a Voice Prosthesis for a patient who has undergone Tracheoesophageal Fistulization/Puncture) ● Insert the voice prosthesis into the fistula; make sure the fistula is properly healed; also make sure that there is no leakage of fluid around or through the prosthesis ● Ask the patient to inhale, occlude the stoma with a finger, and exhale ● Ask the client to produce sound as the air from the lungs enters the P-E Segment through the voice prostheses 357

Laryngitis. Irritated and swollen vocal folds; causes include vocally abusive behaviors and infection; see the following three entries.
L
Laryngitis, Chronic. Irritated and swollen vocal folds of long history; Hoarseness is the primary result; lowered vocal pitch and vocal tiredness also may result; may lead to vocal nodules or polyps. ● Impose vocal rest without whispering ● Reduce vocally abusive behaviors
Laryngitis Sicca. Dryness and atrophy of the laryngeal mucosa, including the glandular structures with a rough, dry, and glazed look to the mucosa; causes include untreated chronic laryngitis, laryngeal radiation, and prolonged use of antihistamine drugs; also often described as dry voice; hoarseness, persistent cough, dry and tickly throat are common symptoms ● Treatment mostly medical (increased environmental humidity and use of lubricating agents) ● Do not recommend voice therapy
Laryngitis, Traumatic. Irritated and swollen vocal folds; result of such vocally abusive behaviors as shouting, screaming, and loud cheering; hoarseness is the primary result. ● Do not recommend voice treatment for such temporary laryngitis as that following enthusiastic participation in 358
Laryngocele ball games; natural period rest (one night’s sleep) may be adequate ● Reduce vocally abusive behaviors if they persist
Laryngocele. Air-filled or fluid-filled sacs that appear on the space between the true and false vocal folds; internal sacs remain within the thyroid cartilage; external sacs protrude above the thyroid cartilage; a combination has both the varieties; the basic condition is a congenital enlargement of the laryngeal ventricle, which may be worsened by straining, coughing, vocal abuse, playing wind instruments, and glassblowing; asymptomatic in infancy; such symptoms as hoarseness of voice, a bulge in the neck (with external laryngocele), and dysphagia may appear during adulthood. ● Treatment is medical and surgical ● Do not recommend voice therapy
Laryngomalacia. A common laryngeal anomaly characterized by excessive flaccidity of the supralaglottic larynx resulting in an epiglottis that is collapsed over the glottis during inspiration; the main symptom is inspiratory Stridor (noisy inspiration); voice is typically not affected.
Laryngopharyngeal Reflux. An upward flow of gastric juices into the laryngeal and pharyngeal structures; irritation caused by such flow; may cause such voice disorders as hoarseness, frequent throat clearing, and granulomas ● Treatment is medical (diet and medications) ● Do not recommend voice therapy
Laryngoplasty. Surgical treatment to improve phonation in people with vocal fold paralysis or weakness; involves medial displacement of vocal folds with the help of implant materials to promote better approximation.

Lesson Plan.
A brief treatment plan which describes shortterm goals and procedures; in case of student clinicians, approved by the clinical supervisor; in preparing lesson plans: ● Use Operational Definitions in writing treatment goals ● Give clear and brief description of procedures to be used
Lipreading. Understanding speech by watching the mouth
L
of the speaker; gaining cues from the movement of the articulators (e.g., the movements of the lips, the tongue, the jaw) and facial expressions; a skill that may supplement limited comprehension of speech through residual hearing; a skill that many children who are deaf learn without much effort; taught to children who are deaf by educators of the deaf.
Liquid Crystal Display (LCD). Flat panel display systems used in computers and other electronic devices (e.g., calculators); used in many devices of Augmentative and Alternative Communication (AAC); contrasted with Cathoderay Tube Display (CRT); backlit displays that have a light source behind the screen are easier to read under varied lighting conditions; contrasted with Cathode-ray Display (CRD).
Lobectomy. Surgical excision of a lobe of an organ; removal of a lobe of lung, brain, thyroid, or liver.
Lobotomy. Surgical incision of the fibers of a lobe of brain. Logical Validity. Consistency of statements that do not violate rules of logic; treatment procedures that may be logically consistent; no assurance that the procedures have experimental support; contrasted with Empirical Validity.
Lombard Effect. Increase in vocal intensity under noisy environmental conditions or under induced masking with 360
Loudness white noise; typically reflexive, but can be brought under voluntary control by instructions and reinforcement; a concomitant effect when masking noise is used to treat stuttering or voice disorders.
Loudness.
A sensation listeners experience as a function of physical intensity of sound; a vocal quality; an aspect of voice that may be disordered; a treatment target in clients with loudness disorders; see under Voice Disorders.

Maintenance Strategy Maintenance Strategy. Methods designed to promote the production of treated communicative skills in natural environments and sustained over time; to be planned from the beginning of treatment; requires the extension of treatment to natural settings and training the client’s significant others to help evoke and reinforce the target skills; all aspects of treatment including stimulus variables, response characteristics, and response consequences should be manipulated to achieve maintenance.
Stimulus Manipulations
● Select common, functional, client-specific stimulus items,
●
M ● ● ●
●
preferably objects; let the client bring stimuli from home (e.g., a girl could bring her toys to serve as stimuli in speech or language training) Select stimuli that are ethnoculturally appropriate for the client; consult with parents in selecting culturally relevant stimuli that the child is familiar with Select colorful, unambiguous, and realistic pictures Select simple and common verbal stimuli that are used to evoke the target responses Vary the audience; have family members and other persons participate as conversational partners in treatment sessions Vary physical setting controls; conduct informal treatment outside the clinic room, in cafeterias, campus walks, library, bookstore, home, and other natural settings
Response Considerations
● Select client-specific and functional responses for treat-
ment targets
● Select ethnoculturally relevant and appropriate treatment
targets
● Select target behaviors that are likely to be produced at home ● Select target behaviors that can easily be expanded into
more complex communicative behaviors
● Train multiple exemplars of each target skill and at each
level of response complexity 364
Management of Behavioral Contingencies ● Take training to complex levels of target skills: always end
treatment with sufficient training at the conversational level
Contingency Manipulation
● Use intermittent reinforcement schedules in the latter
stages of training
● Use conditioned reinforcers (tokens with back-up
reinforcers)
● Delay reinforcement in the latter stages of training ● Let the family members and others watch treatment ses-

sions so they can better understand the treatment targets and teaching methods Train significant others in evoking and prompting the target behaviors at home and in other nonclinical settings Train significant others in reinforcing the production of target behaviors at home and in other nonclinical settings Reinforce generalized responses; have parents and others reinforce generalized productions at home Teach Reinforcement Priming to the client (e.g., teach the client to draw attention to his or her production of target behaviors at home so the ignoring parents can pay attention and reinforce the client) Hold informal Training Sessions in Natural Environments Teach Self-Control (Self-Monitoring) Procedures (e.g., counting one’s target behaviors) Give treatment for a sufficient duration Ensure Follow-Up and arrange for Booster Treatment
Hegde, M. N. (1998). Treatment procedure in communicative disorders (3rd ed.). Austin, TX: Pro-Ed.
Management of Behavioral Contingencies. A clinician’s or a parent’s skill in arranging effective stimuli for target communication skills, requiring the production of specified skills, and in promptly and effectively providing differential feedback for the correct and incorrect productions; inherent to all behavioral intervention techniques; controlled evidence of significant amounts of generality 365
M
Mand-Model
M
supports the use of behavioral contingencies in the treatment of communicative disorders. ● Provide effective stimuli for target behaviors; use pictures, objects, enacted events, instructions, demonstrations, models, prompts, manual guidance, visual and tactile cues, and other stimuli for the target behavior ● Specify the response form; demonstrate what the client is expected to produce ● Give feedback promptly, clearly, naturally, and as frequently as needed ● Positively reinforce imitated or evoked target behaviors with Verbal Praise, Tokens that are exchanged for backup reinforcers, Informational Feedback, Biofeedback, and High Probability Behaviors ● Use Corrective Feedback, Response Cost, Time-Out and Extinction to reduce undesirable behaviors ● Use Differential Reinforcement to teach desirable behaviors that replace undesirable behaviors Hegde, M. N. (1998). Treatment procedures in communicative disorders (3rd ed.). Austin, TX: Pro-Ed.
Mand-Model. A child language intervention method that uses components of Incidental Teaching Method; uses typical adult-child interactions in a play-oriented setting to teach functional communication skills; for procedures, see Language Disorders in Children; Treatment of Language Disorders: Specific Techniques or Programs.
Mands.
A class of verbal behaviors that are triggered by a state of motivation; includes requests, commands, and demands; need to create a state of motivation to teach mands; often reinforced with primary reinforcers. ● Create a state of motivation: • arrange treatment around lunch or breakfast time so food may be used as a reinforcer (hunger is the state of motivation) • hold food in front of the child until the child asks for it 366
Manual Approach • place attractive toys on a high shelf and give them to the child only when requested • offer a food item the child does not like (the child should verbally refuse it) • eat something the child is fond of without offering it (the child should request it) • give a tightly closed jar with candy in it (the child should ask you to open it) ● Reinforce promptly with the displayed or held back item; remove promptly an aversive item presented when the child makes an appropriate response
Manual Approach.
A deaf educational approach that promotes the use of sign language and other manual modes of communication for young deaf children.
Manual Communication. A mode of nonverbal communication that may include sign language, finger spelling, gestures, and other forms of nonoral communication.
Manual Guidance.
Physical guidance provided to shape a response; the Phonetic Placement Method is similar to manual guidance; needed when the client cannot imitate a response; used in treating practically all types of communicative disorders. ● Use your fingers to shape articulators ● Take the client’s hand and make it touch the target picture while training comprehension of commands ● Use tongue depressors to move the tongue to desired positions ● Apply slight digital pressure to the laryngeal area to lower a client’s pitch ● Apply slight pressure on the chin of a child who does not readily open the mouth ● Fade manual guidance to promote the production of target responses without it
Manual Pointing. A method of Augmentative and Alternative Communication in which the client points to a correct 367

mask auditory perception of pure tones or speech during auditory assessment; normally induces the Lombard Effect; used to induce stutter-free speech in stutterers and to induce higher vocal intensity in certain voice clients.
Matching. A method in which subjects of similar characteristics are placed in the experimental and control groups used to evaluate treatment effects; part of the Group Design Strategy. ● Find pairs of subjects with the same or similar characteristics (age, gender, severity of the disorder, socioeconomic status) ● Assign one of the pair to the experimental group and the other to the control group ● Match groups on the basis of group means if pair-wise matching is not possible (the two groups with the same average IQ, for instance)
Maximal Contrast Method. An articulation training method in which word pairs that contrast the most are used to train target phonemes; contrasted with Minimal Contrast Method in which word pairs that differ by one phoneme (e.g., pat, bat); in maximal contrast pair, the words may differ by several features or phonemic contrasts; treatment proce-

Mechanical Corrective Feedback dure the same as those described under Minimal Contrast Method.
Mechanical Corrective Feedback. A method to reduce incorrect responses in treatment; also known as Biofeedback; feedback is presented soon after an incorrect response is made; includes such feedback as provided on a computer monitor for incorrect responses (e.g., undesirable vocal pitch or intensity) and electromyographic feedback on muscle tension.
Melodic Intonation Therapy. An aphasia treatment program that uses musical intonation, continuous voicing, and rhythmic tapping to teach verbal expressions to patients with severe nonfluent aphasia with good auditory comprehension; see Aphasia; Treatment of Aphasia: Specific Technique or Programs for procedures.
Memory Impairments.
Impairments in remembering, recalling, or acting on the basis of remote or recent experiences; impairment in learning or retaining current events or recently experienced events; typically described in such mentalistic or mechanistic terms as storage and retrieval and a variety of presumed mental or neurological processes; nonetheless, almost always it is the presence or absence of actions and behaviors that lead to such presumptions, theoretical speculations, and analogical reasoning; found in many persons with a variety of neurologic and psychiatric disorders; of interest to speech-language pathologists is the memory impairments found in patients of Dementia and Traumatic Brain Injury and to some extent in patients with Aphasia.

external stimulus manipulation (instead of trying to improve some presumed internal and underlying process) and response contingent consequences is effective See Aphasia, Dementia, and Traumatic Brain Injury for symptoms and their association with other communication and related deficits Note that a related skill, attention, if impaired, will result in further deterioration in recent or short-term memory As a speech-language pathologist, integrate memory improvement work with communication training; leave pure, abstract, and process-oriented work on memory to other professionals (e.g., neuropsychologists) Improve patient’s awareness of memory problems by giving contingent feedback on responses that indicate memory lapses (e.g., point out misnaming, failure to recall required experiences, and missed appointments or scheduled activities) Select memory impairments that reduce the patient’s communicative effectiveness; identify functional memory tasks (e.g., remembering names of children or grandchildren) instead of abstract and nonfunctional tasks (e.g., remembering just shown circles or squares drawn on a piece of paper) Improve patient’s orientation before starting a more formal memory management program; note that efforts to improve memory skills may be ineffective with disoriented patients; see Alzheimer’s Disease for suggestions on improving orientation Improve patient’s attention; note that efforts to treat memory skills in inattentive patients is ineffective; alternatively, integrate attentional skills management to memory skill management; consider treatment suggestions offered under Attention Disorders Let the patient help select memory improvement strategies that he or she has used in the past 370

time; use language that is consistent with the patient’s education and current level of functioning Always review what was done in the previous session, give an overview of information about to be offered, frequently review information just offered during treatment sessions, and review again at the end of the session Note if the client learns better by doing things instead of listening to instructions on how to do the same things; if so, schedule activities instead of passive listening to repeated instructions Improving memory skills requires repeated practice of skills and learning; impress on the patient and the family that there is no substitute for repeated practice Conduct frequent but short sessions, instead of long and infrequent sessions In both conversation and treatment sessions, present small amounts of information at a time; test comprehension before moving on to say more Always describe and explain the memory skills targeted for training; be specific and explicit in your description of targeted skills; note that it helps if the patient agrees with your goals and thus better cooperates with your treatment plan Work with health care staff and family to make sure that the goals and procedures are uniformly applied Start with few and the most important functional skills and add additional skills only when the client has mastered the initial skills Speak slowly to the patient and in simple language; train other staff and family members to do the same Highlight important information and alert the patient to crucial information soon to be offered (e.g., ‘‘I am going to tell you something very important’’; ‘‘What I told you is very important’’; ‘‘You should not forget this’’; or ‘‘Listen carefully; this is important for you.’’) 371

Memory Log Books ● Teach the client to develop a Memory Log Book that
helps keep track of activities and appointments
● Teach compensatory skills including written instruc-
M
tions on daily activities (e.g., cooking, shopping, household chores); write prompts on index cards the patient frequently consults or follows during the execution of an activity ● Teach the client to use electronic memory devices, calendars, wristwatches with alarms, and so forth that help keep appointments and remind him or her of scheduled activities ● Teach the client to maintain a pocket notebook on events and activities and train him or her to use it regularly ● Teach family members and health care staff to remind and prompt activities; to help the patient make use of written instructions, memory logs, lists, electronic devices, and so forth; have the family members reinforce the client’s actual use of memory aids and the resulting improvement in behaviors Memory Log Books. A memory aid for patients with memory impairments; consists of written material that helps sustain skills or prompt actions; recommended for patients who have retained at least a basic level of reading and writing skills; not useful for patients who are confused, have leftsided neglect, or have severe uncorrected visual defect ● Design a simple log book that will contain only essential information ● Design a colorful cover for the book so it is easy to locate ● Designate a regular place where book will always be kept; let the health care staff or family members know the place ● Select functional information to be included in the log book; consult with the patient, staff, and the family members in making this selection ● Include the patient’s biographical information (name, age, address, phone number, family members’ names); the current moth, year, and the name of the hospital; names of 372
Mendelsohn Maneuver main health care workers and individual clinicians treating the patient ● Train the patient to take the book to all appointments, including treatment sessions ● Include in the book pictures and names of therapists and family members; train the client to frequently consult this information to facilitate memory for their names and faces ● Designate a single health care worker who will help maintain, update, and modify the book as found appropriate ● Divide the book into easily identifiable sections, preferably of different color; organize information in the sections for easy consultation (e.g., a section on treatment session appointments, a section on daily activities, a section on medications and their schedules, a section on recreational activities, etc.) ● Train the client to consolidate all written forms of memory aids into the log book and not have multiple and odd pieces of information strewn around ● Teach the patient to write down information and then to periodically review the written information to act on it Mendelsohn Maneuver. A swallowing maneuver that helps elevate the larynx more and for longer duration, resulting in an increased width and duration of cricopharyngeal opening; see Dysarthria; in implementing this maneuver: ● Educate the patient about the elevation of larynx (tell him or her about the Adam’s apple or voice box going up) ● Have the patient palpate the elevation of the larynx when he or she swallows saliva several times ● Instruct the patient to hold the larynx up for a longer duration (several seconds) as he or she swallows; give such instructions as ‘‘Swallow long and strong’’ or ‘‘Stretch out the swallow’’ Meninges.

problems are a significant aspect of retardation; mostly, the treatment procedures for Language Disorders in Children are applicable with the following special considerations: ● Recommend or initiate treatment as early as possible ● Get the family involved in early Language Stimulation ● Get the help of other specialists including special educators and psychologists ● Make a comprehensive evaluation of the client’s skills and deficiencies ● Consider the academic or occupational demands made on the client; select targets that help meet those demands; in the case of children, work closely with teachers in selecting target behaviors for treatment ● Select target behaviors that are functional (useful) to the client in educational, occupational, family, and social situations ● Design a comprehensive treatment plan that is most likely to include articulation and language and perhaps voice and fluency as well ● Select for initial training communicative behaviors that will produce the most effect in natural settings and in classrooms in case of children (e.g., select articulation training before language training if this leads to improved communication sooner; select language training if teaching a few functional words is the priority; teach a few functional signs before verbal expressions in the case of nonverbal and severely retarded children) ● Sequence the target behaviors carefully; use small step increments ● Model the target responses frequently; initially reinforce approximations of modeled responses; gradually require better approximations and finally require an exact match, if that is practical ● Fade modeling in gradual steps ● Shape responses whenever the client cannot imitate modeled responses 374

but soon loosen the structure to resemble naturalistic situations Train in varied naturalistic settings to promote generalized production Use primary reinforcers initially and fade them; eventually use only verbal reinforcers Shape complex language behaviors in successive stages Train parents and teachers in prompting and reinforcing newly acquired communicative behaviors Implement a systematic maintenance program Consider nonverbal means of communication (e.g., American Sign Language) or Augmentative and Alternative Communication when appropriate Follow up and arrange for booster treatment
Metronome-Paced Speech. A method used to slow down the rate of speech; the client is asked to pace a syllable or a word to each beat of a metronome; used in the treatment of stuttering, cluttering, and certain forms of dysarthria; see also Stuttering, Treatment; Treatment of Stuttering: Specific Techniques or Programs and Treatment of Dysarthria. ● Begin treatment with a slow beat that reduces the rate of speech so that stuttering or cluttering is markedly reduced or speech intelligibility of dysarthric clients improves ● Have the client practice slow speech until fluency or improved speech intelligibility are stabilized ● Fade the metronome by gradually increasing the rate of its beat until the speech rate and prosody approximate the normal; note that this step is especially needed for persons who stutter or clutter.
Minimal Contrast Method. A method of treating articulation disorders in both children with developmental articulation disorder and adults with dysarthria; based on the 375
M
Minimal Contrast Method
M
assumption that it is necessary to teach the semantic differences between a child’s (misarticulated) production and the correct adult production; involves the use of word pairs that differ only in one phoneme (hence the name, minimal contrast); also known as minimal-pair method or approach; see also Maximal Contrast Method. ● Select word pairs that differ by only one phonemic feature (e.g., key-tea; pat-bat; four-pour); note that for a given client, one of the phoneme is the erred one and the other is the target (e.g., in the case of /t/ substitution for /k/, a minimal pair will be tea-key) ● Select 8 to 10 word pairs for a phonemic contrast (e.g., to eliminate final consonant deletion, select such word pairs as bow-boat, bee-beet, toe-toad, and pie-pine) ● Select pictured stimulus items to represent both the words of all the pairs ● Place the pictures representing the word pairs in front of the child ● Model a given word pair (e.g., bow-boat) and ask the child to imitate; reinforce correctly imitated productions or approximations; give several trials ● Move to spontaneous naming task; ask the child to say a word, and point to it; then hand the child what he or she names (not what he or she points to if pointing and saying do not match, e.g., if the child points to beet but says bee, give the child bee, not beet that was pointed to) ● When the child does not accept the wrong picture (e.g., you handed bee when he or she pointed to beet, which was wanted), give corrective feedback; model beet, emphasizing /t/, and ask the child to imitate it ● Reinforce correct responses; train other pairs ● Arrange controlled play activities in which the target sounds and words are practiced in conversational speech (e.g., a toy soap used to pretend to wash hands, pots, dolls, and so forth while talking about the activity)
376

Multiple Baseline Across Behaviors Design. A single subject design in which several behaviors are sequentially taught to show that a behavior changed only when brought under treatment and untreated behaviors remained unchanged; helps rule out extraneous variables leading to the conclusion that the treatment was effective. ● Select three or more target behaviors (e.g., three or more phonemes, grammatic morphemes) ● Establish baselines on all selected target behaviors on discrete trails and in conversational speech ● Teach the first behavior to a Training Criterion ● Repeat baselines on the remaining untreated behaviors ● Teach the next behavior and repeat the baselines on the remaining untreated behaviors ● Continue to alternate baselines and treatment until all the behaviors are trained ● Expect the untreated behaviors not to change; if changed, note that the experimental control is weakened and it is difficult to claim treatment effectiveness 379

treatment, conclude that treatment was effective and that no other factor is responsible for the changes Multiple Baseline Across Settings Design. A singlesubject design in which a behavior is sequentially taught in different settings to show that the behavior changed only in a treated setting and hence the treatment was effective. ● Baserate a target behavior in three or more settings (e.g., clinic, home, school, or office) ● Teach the behavior in one setting (e.g., fluency in the school clinician’s office) ● Repeat the baserates in the remaining untreated settings ● Teach the behavior in another setting (e.g., fluency in the classroom) ● Continue to alternate baserates and teaching in different settings until the behavior is trained in all settings ● Conclude that the treatment was effective only if the repeated baserates show that the target behavior changed in a setting only when treatment was offered in that setting Multiple Baselines Across Subjects Design. A singlesubject research design in which several subjects are treated sequentially to show that only treated subjects changed and hence treatment was effective. ● Select a target behavior that needs to be taught to three or more clients ● Baserate the target behaviors in all subjects ● Treat one of the subjects ● Repeat the baserates on the untreated subjects ● Treat the second subject ● Repeat the baserates on untreated subjects ● Alternate treatment and baserates until all the clients are trained ● Conclude that the treatment was effective only if the repeated baserates show that clients showed positive 380

as given under Interobserver Reliability Hegde, M. N. (1994). Clinical research in communicative disorders: Principles and strategies (2nd ed.). Austin, TX: Pro-Ed.
Replication. Conducting repeated research to show that a
R
given procedure works with different clients, in different settings, and for different clinicians; important in treatment efficacy research; includes direct replication and systematic replication; both designed to show treatment Generality; one of the Treatment Selection Criteria. Direct Replication. The same investigator repeats the same treatment experiment in the same setting but with different subjects who have the same characteristics as the original subjects. ● Initially, show that a treatment works with some clients ● Select different clients who share the same personal (age, gender, health) and clinical characteristics (severity, age of onset) as the original subjects ● Repeat the treatment experiment ● Analyze the results to evaluate generality of the treatment method Systematic Replication. The same or different investigators repeat a treatment experiment in different settings, with clients who have different characteristics than the original clients; may even include clients with totally different diagnoses. ● Initially, an investigator shows that a treatment is effective with a sample of clients ● The same or a different investigator repeats the treatment research with another sample, with different personal (gender, age, health) and clinical characteristics
424
Response Class (severity, age of onset) characteristics, and in a different setting than the original ● The investigator analyzes the results to evaluate the broader generality of the treatment method Hegde, M. N. (1994). Clinical research in communicative disorders: Principles and strategies (2nd ed.). Austin, TX: Pro-Ed.
Response Class. A group of responses created by the same or similar contingencies; functionally, but not necessarily structurally, similar responses; good treatment targets because there is generalized production within a class and discrimination between classes.
Response Complexity. Different topographic levels of a target behavior; structural complexity of communicative behaviors typically create a sequence of treatment. ● Teach words before phrases ● Teach phrases before sentences ● Teach sentences before conversational speech
Response Cost. A direct response reduction strategy in which the production of each response scheduled for reduction results in the loss of a reinforcer. In the Earn and Lose variety, clients earn a token for every correct response and lose one for every incorrect response. In the Lose-Only variety, the client who receives unearned tokens at the beginning of a session loses one for every incorrect response.
Earn and Lose
● Give a token, to be exchanged for back-up reinforcers, for
correct responses
● Take a token away each time the client produces an incor-
rect response
● Exchange the tokens the client still possesses for back-up
reinforcers at the end of the session
Lose-Only
● Give a certain number of tokens at the beginning of a
session
425
R
Response Generalization ● Take a token away each time the client produces an incor-
rect response
● Exchange the tokens the client still possesses for back-up
reinforcers at the end of the session
Response Generalization. Production of unreinforced (new, untrained) responses that are similar to trained responses; a goal of treatment; typically achieved through various strategies designed to promote Generalization because stimulus generalization in language training also involves response generalization. Response Mode Generalization. Production of unreinforced responses in a mode not involved in training. ● Train skills in a certain mode (e.g., fluency in oral reading) ● Probe to assess generalized production (fluency in conversational speech) ● If there is no generalization, train the skills in that mode (fluency in conversational speech) Response Recording Sheet. A prepared sheet for recording correct, incorrect, and no responses given in treatment sessions. ● Design and use a response recording sheet similar to the following; modify as necessary

Response Reduction Strategies Response Reduction Strategies. A collection of procedures that help decrease undesirable responses; include Direct Methods of Response Reduction and Indirect Methods of Response Reduction.
Response Substitution. Increase in an undesirable behavior when another behavior is reduced; exemplified by increased frequency of wiggling in the chair when a child’s disruptive hand movements are reduced by a response reduction method. ● Apply a response reduction strategy to the newly emerged undesirable behavior ● Apply such strategies sequentially if you have to
Response Unit.
A training target in the Paired Stimuli Approach to treating articulation disorders (described under Articulation and Phonological Disorders; Treatment of Articulation and Phonological Disorders: Specific Techniques or Programs); the client is asked to produce a key word and a target word as a single response unit (e.g., this-bus); the client earns one reinforcer only by correctly producing the target sound in both of the words.
Restitution. An element of overcorrection in which the person eliminates the effects of his or her misbehavior and then improves the situation; described under Imposition of Work. ● Ask the child who disorganizes your stimulus materials to reorganize them ● Next, ask the child to organize the toys on the floor (the disorganized toys were not the child’s making)
Reversed Imitation. Clinician’s imitation of a child’s utterance during indirect language stimulation; in the operant Imitation, it is the client who imitates and the clinician who models.
Right Hemisphere Syndrome. A syndrome of brain injury and its consequences sustained in the right cerebral hemisphere; may be caused by cerebrovascular accidents, 427
R
Right Hemisphere Syndrome tumors, head trauma, or various neurological diseases; associated with perceptual, attentional, emotional, and communicative deficits; varying degrees of functional involvement depending on the site, nature, and extent of damage.
Treatment: General Considerations
● Note that treatment research on the techniques typically

● ● ●
suggested is limited and in many cases, nonexistent; recommendations are based on clinical experience of several clinicians; use all suggestions with caution and with a view to collect data Counsel the family about communication treatment soon after the onset Note that some clinicians prefer to teach specific skills while others prefer to treat presumed underlying processes; process approach needs to demonstrate that skills improve when underlying processes are targeted for treatment; in practice, the two approaches may be integrated Begin treatment as soon as it is practical Select the client-specific treatment targets that: • will result in the most improvement in family, social, and vocational communication • help build other, more advanced communication skills • help focus on communicative treatment targets (e.g., attentional deficits may have to be treated before other language skills) • the clients can imitate Develop stimulus materials that: • range from simple to progressively more complex and from fewer to greater number of elements • are clear, unambiguous, and relatively concrete • are familiar, meaningful to the client, and attractive Establish baselines of target behaviors Provide extensive and intensive practice Be aware that there is no controlled clinical evidence to support the use of computerized cognitive rehabilitation programs 428
Right Hemisphere Syndrome ● Structure treatment sessions initially and loosen them as

the client becomes more proficient in producing the target responses Use instructions, modeling, and prompts in all stages of treatment Fade the special antecedents used in early stages of treatment Shape the target behaviors Give prompt and effective feedback Work with the family members to promote generalization and maintenance
Treatment: Targets and Procedures Treat Lack of Awareness of Problems Experienced ● Give immediate verbal feedback on errors ● Give visual feedback on errors ● Tape record and replay the speech to the client and discuss the errors ● Teach the client Self-Control (Self-Monitoring) skills Treat Impaired Attention ● Shape sustained attending behaviors with changing criterion (Changing Criterion, Treatment Procedure) ● Reinforce the client for paying attention to the stimulus material and for maintaining eye contact ● Structure the initial treatment sessions and reduce distractions, including noise ● Give alerting stimuli before presenting the treatment stimuli (e.g., ‘‘Look at me’’ before modeling a response, ‘‘Get ready, here comes the next picture’’ before presenting the stimulus picture; touching the client before presenting a treatment stimulus) ● Draw attention before you speak to the client (e.g., ‘‘Listen, I am going to tell you something.’’) ● Vary the treatment stimuli, drop unattractive stimuli, use clear and forceful stimuli ● Give frequent, brief breaks in the initial phase of treatment; reduce the number and duration of the breaks gradually 429

Right Hemisphere Syndrome ● Introduce gradually some distracting stimuli while still
R
reinforcing attention to treatment tasks Treat Visual Neglect ● Note that the most commonly used strategy to treat neglect is to force attention to that side with a variety of cues and prompts ● Use printed material or any means that would force attention to the neglected side ● Teach the patient to keep a finger on the left margin while reading and track back to it before beginning a new line ● Color the left-side margins, draw a colored line through the margin, or use other discriminative stimuli to force attention to the left side of reading texts; fade such stimuli ● Tell the patient to ‘‘Look to the left’’ when the client reaches the end of sentences; fade such verbal cues ● Teach clients to recognize that what they read does not make sense; teach them to quiz themselves about what they read ● Design reading materials with large print and progressively smaller print and ask the client to read them aloud Treat Impulsive Behaviors ● Teach the client to wait and withhold responses ● Give nonverbal signals to delay responses ● Fade the noverbal signals and introduce verbal signals to wait, withhold, and delay Treat Pragmatic Language Skills ● Teach the client to initiate conversation; have the client discuss various topics in which you teach various skills by modeling them, ask the client to use them, and reinforce the client for using them; for instance: • teach the client to introduce the topic explicitly • teach the client to give background information on narratives and stories 430
Right Hemisphere Syndrome • teach the client to periodically restate the topic of discussion • prompt the client to maintain focus on the main topic • teach the client to ask such questions as ‘‘Do you follow me?’’ or ‘‘Do you understand?’’ • give corrective feedback ● Teach the client to request clarification when messages are not understood (e.g., ‘‘Please repeat that,’’ or ‘‘I do not understand.’’) ● Teach the client to maintain eye contact during conversation; use such verbal stimuli as ‘‘Look at me’’ ● Reinforce progressively longer durations of topic of maintenance ● Teach the client to take turns in conversation; stop the client for inappropriate turn taking (e.g., interrupting you) ● Use the PACE program (Promoting Aphasics’ Communicative Effectiveness; described under Aphasia; Treatment of Aphasia: Specific Techniques or Programs) for teaching social communication Treat Impaired Reasoning Skills ● Teach the client to think and plan (e.g., discuss how the client might plan a vacation; help the client move in a logical manner) ● Pose different kinds of problems one might encounter in real life and ask the client to solve them (e.g., ‘‘How do you buy an airplane ticket?’’) Treat Impaired Inference ● Tell stories and ask questions to evoke implied information ● Describe situations that require the client to draw logical conclusions Treat Impaired Recognition of Absurdities ● Show pictures that depict logical and absurd events and ask the client to separate them (e.g., picture of a cat chasing a rat and picture of a rat chasing a cat) 431
R
Right Hemisphere Syndrome ● Present verbal or written statements that are logical or
absurd and ask the client to separate them
● Ask the client to explain why a statement is absurd or
R
logical Treat Impaired Comprehension of Metaphors or Idioms ● Ask the client to select statements that give literal meanings ● Asking the client to sort out literal and figurative statements ● Set up hypothetical situations that require such judgments Treat Comprehension of Figurative Meanings ● Begin with nonliteral meanings that the client presently uses and understands ● Provide multiple meanings for a single statement ● Discuss the difference between what the statement apparently says and what it means ● Use stimuli that the client was familiar with and used premorbidly Treat Comprehension of Humor ● Associate captions with the cartoons ● Link the punch line with the body of the joke Teach Compensatory Strategies ● Monitor the comprehension of the speaker’s utterance ● Teach the use of such functional memory aids as lists of things do, writing down appointments, having a checklist of things to do before leaving the house, keeping related things together, and so forth ● Teach Self-Control (Self-Monitoring) skills including the generation of memory aids ● Teach the client to stop and self-correct when errors are made ● Make a few socially appropriate and inappropriate statements and ask the client to evaluate them ● Have the client evaluate social appropriateness of his or her own productions 432

Sample Sample. A smaller number of individuals selected from a larger population for a research study.
Satiation. Temporary termination of a drive or need because it has been satisfied; a potential problem with Primary Reinforcers (e.g., food). ● Give only small amounts of food or drink to reinforce individual responses ● Let the client accumulate food that he or she can eat later ● Arrange treatment sessions, especially with infants and toddlers who need primary reinforcers, around breakfast or lunchtime ● Ask parents to withhold the primary reinforcers you plan to use before coming to treatment sessions
Scanning in Augmentative Communication. An in-
S
direct message-selection method in augmentative communication; various messages are typically displayed on a computer screen or special devices; the client uses switches to select an intended message; scanning with electronic displays include the following types: ● Auditory scanning: Useful for blind AAC users; the user gets auditory cues that tell available choices (e.g., Things to eat, Things to wear spoken with one voice); the client then selects the specific category among the presented categories; the items within the category selected are spoken with another voice (e.g., hamburger, milk); the client then selects the individual item ● Circular scanning: The screen displays message or symbol choices in a circular manner, and the client presses a switch to highlight the desired item or an intended message ● Direct scanning: The screen displays various message choices; the client holds a switch pressed down; consequently, the indicator (cursor) moves through the list; the client releases the switch as soon as the cursor is on the desired item, which is then highlighted 436
Schedules of Reinforcement ● Group item scanning: The screen displays messages or
● ●
●
●
symbols in groups; the client first highlights a group (e.g., food items) and then an individual item in the group (a glass of juice) Multiple switch scanning: Highlighting messages or symbols with the help of two or more switches. Predictive scanning: Scanning based on previous selections; once a selection is made, the device presents only those choices that may be selected next; speeds up the selection process Row column scanning: Selecting a message of symbol by first highlighting an entire row and then an individual item within the row Step linear scanning: Scanning item-by-item with a switch that moves the cursor across choices; the user stops the cursor when it highlights the desired item
Schedules of Reinforcement.
Different patterns of reinforcement that generate different patterns of responses; include Continuous Reinforcement schedules and Intermittent Reinforcement schedules. ● Use continuous reinforcement schedule in the beginning of treatment ● Shift to an intermittent schedule as learning becomes more stable
Script.

Self-Control. A behavior that monitors and modifies other behaviors of the same person; a necessary skill in maintaining clinically acquired communicative behaviors.
Self-Control (Self-Monitoring) Teaching Procedures.
S
Techniques of monitoring one’s own behavior to effect significant and positive changes; useful to teach these techniques to clients within a Maintenance Strategy: take note of the examples and extend them to other disorders and other kinds of strategies: ● Teach clients to discriminate their own incorrect and undesirable responses; for instance: • model a child’s misarticulated sound production and ask the child to listen to them • demonstrate a stuttering person’s associated motor behaviors • model a child’s phrases or sentences that do not contain required grammatic morphemes (e.g., ‘‘Two cup’’ or ‘‘Boy walking’’) • play back a taped sample of client’s speech to point out undesirable voice quality ● Teach clients to contrast their desirable and undesirable responses; for instance: • contrast easy and hard glottal attacks of a voice client or a fluency client by modeling the two kinds of phonatory initiations • contrast incorrect and correct productions of phonemes by modeling them 438
Self-Control Teaching Procedures • contrast correct and incorrect sentence forms (e.g., ‘‘Two cup’’ and ‘‘Two cups’’) • contrast the desirable lower pitch with the client’s excessively high pitch by modeling the two pitch levels or by tape-recording the client’s voice that might catch both the levels ● Teach clients to measure their behaviors reliably; for instance: • ask a client to measure his or her dysfluencies in selected situations outside the clinic and submit the data • ask a client to measure the frequency of his or her vocally abusive behaviors for 3 days and submit the data • ask a client to measure his or her misarticulations in certain specific situations and submit the data • have clients tape-record a home speech sample and play it as you give feedback on the target behaviors to be measured ● Let clients measure their behaviors along with you in treatment sessions; note that children, too, can learn to make a tally mark to measure correct productions of sounds, grammatic morphemes, voice qualities, and so forth; for instance: • in the treatment sessions, ask the client to chart his or her own correct and incorrect productions of target phonemes along with you • ask a fluency client in therapy to chart his or her own dysfluencies, hard and abrupt voice onset, excessively fast speech, easy onset, and appropriate rate • ask an apraxic client to chart correct and incorrect articulatory movements • ask a child in language therapy to chart sentences with and without the target grammatic features • ask a voice client in therapy to chart his or her desirable vocal qualities ● Give clients frequent feedback on their measurement to improve their skill; for instance: 439
S
Self-Control Teaching Procedures
S
• give all clients feedback when they fail to record their correct and incorrect responses; point out the characteristics of those responses, model them if necessary, and ask them to resume their charting • throughout the session give them informative feedback (‘‘You and I agreed on three of the five instances’’ and ‘‘This time, you and I agreed on four of the five instances.’’) • monitor the progress and make sure the clients’ skill in measuring their behaviors improves over the sessions ● Teach clients to monitor their newly acquired skills by measuring them outside the clinic; for instance: • ask the fluency client to keep a pocket record of his or her use of slower rate or gentle phonatory onset; minimally, ask the client to gain a clear impression of the frequency of their use • ask a voice client with excessively soft voice to keep a record of the number of social situations in which he or she spoke with adequate loudness • ask a client with aphasia to keep a record of the number of times he successfully recalled his wife’s name in a given day ● Teach clients to generate signals and prompts for their own actions in the natural environment; for instance: • ask a patient with aphasia to write down the names of family members and frequently consult the list before engaging in conversational speech • ask a client to wear electronic devices that remind him or her of appointments, to slow down the speech, to speak more softly or loudly, and so forth ● Teach clients to pause after they produce a wrong response both in the clinic and outside the clinic; for instance: • teach a stuttering client to pause briefly after each dysfluency and say the same word fluently without your help 440
Self-Control Teaching Procedures • teach a voice client to pause soon after a hard glottal attack is produced and start again with a softer attack without your help • teach a child in articulation therapy to stop as soon as he or she produces a target sound incorrectly without your help • teach a client in apraxia therapy to stop as soon as a wrong articulatory gesture is initiated and then initiate the correct gesture without your help ● Teach clients to correct their own mistakes or nontarget responses • initially, give corrective feedback for every incorrect response • tell the client that you will on occasion not give correct feedback and the client should catch himself or herself making a wrong response and immediately correct the mistake without help • withhold corrective feedback on certain occasions • if the client does not immediately self-correct, give corrective feedback; remind the client that he or she should self-correct without your help • continue the procedure until the client reliably selfcorrects; reduce the frequency of corrective feedback further while maintaining self-corrections ● Teach clients to anticipate problems and take corrective actions • teach a person who stutters to practice saying ‘‘Hello’’ with appropriate airflow when the telephone starts ringing • teach an aphasic client to practice names of people who are expected to visit shortly • teach a voice client with vocal abuse to reduce talking before a scheduled and unavoidable speech to be given to a group • teach another voice client to drink more water to ward off vocal problems related to vocal dryness 441
S
Self-Talk ● In group therapy, teach clients to correct other partici-
pants’ errors • in a group therapy involving children who have received treatment for stuttering, teach each child to monitor other children’s speech rates and to give appropriate feedback • in group therapy involving aphasic clients, teach each to remind the other to practice specified skills (e.g., selfcueing words with the first word phoneme) • in language group therapy, teach each child to monitor the use of a specific grammatic feature in other children and give appropriate feedback
Self-Talk. A child language intervention procedure in which the clinician describes his or her own activity while playing with a child; procedure described under Language Disorders in Children; Treatment of Language Disorders: Specific Techniques or Programs.

Service Delivery Models. Different arrangements of
S
providing assessment and treatment services to children with communication disorders, include the Collaborative Model, the Consultant Model, the Language-Based Classroom Model, and the Pull-Out Therapy Model.
Shaping. A method of teaching nonexistent responses that are not even imitated; also known as successive approximation; supported by experimental evidence; highly useful in teaching a variety of skills. ● Select a terminal target response (e.g., the production of /m/ in word initial positions) ● Identify an initial component of that target response the client can imitate (e.g., putting the two lips together) 442
Side-Effects of Punishment ● Identify intermediate responses (e.g., humming or other
kinds of vocalizations, opening the mouth as humming is continued) ● Teach the initial response by modeling and immediate positive reinforcement (e.g., putting the lips together on several trials) ● In successive stages, teach the intermediate responses (e.g., adding humming when the lips are closed; opening the mouth when the humming is continued; adding other sounds to form words) ● Continue until the terminal response is taught
Side-Effects of Punishment. Undesirable effects of punishment procedures; include emotional reactions, aggressive reactions, unexpected increase in the punished response, increase in a different response than the one punished, and so forth; to be eliminated or minimized by prudent use of response reduction methods. ● Always use positive reinforcers for desirable behaviors ● Keep reinforcement:punishment ratio in favor of reinforcement ● Shape a difficult response to avoid using response reduction methods ● Consistently apply response reduction methods to all undesirable behaviors ● Remove or reduce reinforcement for undesirable behaviors ● Never associate response reduction methods with positive reinforcement
Significant Others. People who typically interact with a client on a daily basis; include family members, teachers, friends, colleagues, baby sitters, and health care workers; important in helping the client learn and maintain communicative behaviors; recipients of training within a Maintenance Strategy.

Single-Subject Design Strategy. Methods of demonstrating treatment effects by showing contrasts between conditions of no treatment, treatment, withdrawal of treatment, and other control procedures; typically, all subjects selected receive treatment (no control group); includes, among others, ABA Design, ABAB Design, and Multiple Baseline Design; contrasted with Group Design Strategy.
Social Reinforcers. A variety of conditioned reinforcers frequently used in treatment sessions; include verbal praise, attention, touch, eye contact, and facial expressions; resistant to satiation effect; may not work with nonverbal clients. ● With children who are nonverbal, profoundly retarded, and very young (infants and toddlers), pair social reinforcers with primary reinforcers ● Eventually, fade the primary reinforcers and maintain the responses on social reinforcers only
Soft Articulatory Contacts. A stuttering treatment tar-
S
get; includes relaxed, easy, and soft contact of articulators in speech production; used in conjunction with such other techniques as Airflow Management and Rate Reduction; for procedures see Stuttering, Treatment; Treatment of Stuttering: Specific Techniques or Programs.
Spasmodic Dysphonia. A voice disorder characterized in most cases by severe overadduction of vocal folds and strained or choked-off voice quality; in some cases, phonation may be impossible; in other cases, characterized by sudden abduction of folds and resulting aphonia; of unknown etiology; possible neuropathology; voice therapy is not particularly helpful although several techniques, including relaxed, easy, and less effortful phonation; the yawn-sigh method; auditory masking; amplified voice feedback, laryngeal massage, and other kinds of digital manipulations; none 444
Spastic Dysarthria has produced lasting treatment effects; some clinicians combine voice therapy with medical management in a team effort; current medical management includes: ● Injection of Botox (botulinum toxin A) into one or both of the vocal folds to induce paralysis of the folds; some data suggest the best results are with unilateral injection • initially, the voice is weak and breathy, which improves with voice therapy • voice therapy is designed to eliminate habitual over adduction and effortful phonation by teaching more relaxed phonation • reinjection may be needed as the effects last only a few months ● Recurrent laryngeal nerve sectioning; a surgical procedure in which the recurrent laryngeal nerve is cut. • procedure has not produced long-term favorable effects and, in some cases, the symptoms worsen; the laryngeal nerve also may regenerate, resulting in the symptoms return • need to be combined with voice therapy; procedures to raise the pitch, head position changes, and digital manipulation of the larynx have all been clinically tried and found to be helpful to varying degrees
Spastic Dysarthria. A type of motor speech disorder; its neuropathology is bilateral damage to the upper motor neuron (direct and indirect motor pathways) resulting in weakness, spastic paralysis, limited range of movement, and slowness of movement; may affect all aspects of speech; major speech problems include strained-strangled-harsh voice, hypernasality, slow rate, consonant imprecision, and monopitch and monoloudness; select appropriate treatment targets and procedures described under Treatment of Dysarthria; see Dysarthria: Specific Types.
Specific Language Impairment (SLI).
Language disorders in children who are otherwise normal although some 445
S
Specific Voice Facilitating Techniques may have subtle cognitive deficits; different language skills may be somewhat differentially affected; pragmatic skills may be better than syntactic and morphological skills; a diagnosis made on negative grounds (no other factor, such as mental retardation or neurologic deficits, explains the disorder); some believe that SLI suggests limited language skills with no pathology; treatment procedures are the same as those for Language Disorders in Children.
Specific Normal Voice Facilitating Techniques. A collection of voice therapy procedures used to promote normal voice productions; see Voice Disorders; Specific Normal Voice Facilitating Techniques.
Stimulus Generalization. Production of a newly learned response to stimuli not used in training; an important goal of intervention; to promote stimulus generalization. ● Use a variety of stimuli during treatment ● Use common stimuli ● Ask clients to bring objects, toys, books, and so forth from home to use as stimuli ● Train multiple exemplars ● Periodically Probe the production of target behaviors to assess their generalized productions
Stimulation Versus Treatment or Teaching. In lan-
S
guage intervention, stimulation tends to be less directed, more naturalistic, without specific language targets, without a requirement that the child imitate modeled responses, and is often implemented by nonclinicians; treatment or teaching tends to be more clinician-directed, less naturalistic, with specific language structures as targets, with the requirement that the child imitate modeled responses, and often implemented by speech-language pathologists.
Stimulus Withdrawal. A group of procedures used to reduce incorrect responses during treatment; a reinforcer or a reinforcing state of affairs is removed as soon as an incorrect response is made; includes Time-Out and Response Cost. 446
Story Grammar Story Grammar. The structure of narratives which may be treatment targets for children with language disorders; described under Language Disorders in Children; Treatment of Language Disorders: Specific Techniques or Programs.
Stridency. A voice disorder characterized by an unpleasant, shrill, and metallic-sounding voice; caused by excessive pharyngeal constriction and an elevated larynx. ● Use the Chewing Method ● Model and contrast good vocal production with a strident production ● Lower the pitch; use Glottal Fry ● Teach relaxation ● Teach oral openness ● Use Yawn-Sigh method
Stridor. A harsh and shrill (high-pitched) sound during breathing; often found in persons with laryngeal obstruction; laryngeal stridor is associated with various laryngeal pathologies including congenital laryngeal cyst, congenital laryngeal papilloma, congenital subglottic stenosis, and laryngocele; treatment is medical.
Stuttering. A disorder of fluency characterized by excessive amounts of Dysfluencies, excessive durations of dysfluencies, and unusual amount of muscular effort in speaking; has varied definitions including an involuntary loss of speech motor control, part-word repetitions and sound prolongations, efforts to avoid stuttering, a social role conflict, and so forth; may be associated with avoidance of certain words and speaking situations; experience of negative emotions and expression of negative verbalizations about himself or herself and about listeners.
Stuttering, Treatment. Stuttering has varied treatment procedures; only a few have been tested for their efficacy; some are questionable; some have uncontrolled clinical support; several are purely rational; most clinicians combine 447
S
Stuttering: A Comprehensive Treatment certain effective components of treatment to create somewhat personal programs; airflow management, gentle phonatory onset, and rate reduction through prolonged syllables are common elements across diverse contemporary treatment programs; these programs are empirically supported with some experimental evidence.
1. A Contemporary, Comprehensive Treatment Procedure for Stuttering in Older Children and Adults ● The goal of treatment is to reduce the rate of dysfluen-
S
cies in conversational speech to less than 1% in clinic speech samples and no more than 5% in everyday situations by: • teaching the client to manage his or her speechrelated airflow properly • teaching the client to initiate speech softly and gently • teaching the client to prolong syllable durations to reduce the speech rate • shaping normal prosodic features of speech and stabilizing fluency • strictly managing the behavioral contingency by giving prompt positive and corrective feedback • shifting treatment to more naturalistic settings • training significant others to manage the skills in the natural environment to promote maintenance of fluency over time and across situations • following up the client periodically and giving booster therapy when needed ● Make a thorough assessment; determine the forms and the frequencies of stuttering in both conversational speech and oral reading in clinical and extraclinical situations; consult the cited sources and the PGASLP ● Before you start treatment, take note of suggestions under Measure dysfluency rates in all treatment sessions and Vary the treatment procedures to suit the individual client, both found at the end of this main entry 448
Stuttering: A Comprehensive Treatment ● Define stuttering in a measurable way; note that mea-
suring specific dysfluencies generally leads to better interobserver reliability ● Baserate stuttering in the clinic • take extended conversational speech samples • count all types of dysfluencies and the number of words spoken • calculate the percent dysfluency rate • continue to record brief conversational speech samples in the next two sessions during the first 5 minutes • take additional samples if the three-sample dysfluency rates are highly divergent ● Select the three target fluency skills that are incompatible with stuttering, commonly used, and known to be effective in establishing stutter-free speech: Airflow Management, Gentle Phonatory Onset, and Rate Reduction through syllable prolongation; all described later under Treatment of Stuttering: Specific Techniques or Programs. ● Counsel the client and the family about the treatment program • Give an overview of the treatment program and its rationale (essentially tell them that the method prevents stuttering and helps practice fluency skills) • point out its known effects and research data that support its use • point out its drawback, which is initially an unacceptable artificial-sounding fluency • point out its advantages: it teaches fluency skills that the client can fall back on at any time in the future • caution about the potential need for Booster Therapy in the future; tell them that brief periods of repeated booster treatment over a period of several years may be needed • impress on the client and the family that a relapse of stuttering does not mean the treatment has failed; 449
S
Stuttering: A Comprehensive Treatment

decision points and decision criteria are specified; however, with some experience, clinicians begin to skip steps, move faster or slower, and even skip a particular target skill if that does not make a difference try if only a rate reduction would be sufficient for a given client; add airflow only if it enhances the rate of improvement (quickly eliminates certain kinds of dysfluencies) de-emphasize or stop explicitly monitoring a skill sooner or later if you did employ all the skills to begin with; probe to see if fluency is sustainable without an explicit monitoring of that skills use oral reading initially if that seems to give a better control on the fluency skills; some clients do better in oral reading where they do not have to focus on what to say start treatment at any level the client can handle the skills; some need not be started at the word level; phrases might work and, with a few clients, even short sentences may be the starting point if you did start at the word level, try moving to the short sentence level briefly to see if stutter-free speech can be sustained; if so continue at this level (thus skipping the phrase level) let the client’s performance data dictate the sequence, speed, relative emphasis on skills, and the number of steps involved in treatment

structured play situation to evoke and manage speech from the child Experiment informally with all three targets used with older children and adults: airflow management, gentle phonatory onset, and rate reduction through syllable prolongation; possibly, with very young children, only a slower rate may be effective in inducing stutter-free speech; if so, skip the others; most likely to be skipped is airflow management; the next most likely to be skipped is gentle phonatory onset; the younger the child, the more likely it is that you will use only slow speech Counsel the family about the treatment program, its known effects, its drawback (initially unacceptable, artificial fluency), and the potential need for booster therapy in the future; impress on them the need to regularly work with the child at home and the critical role they play in fluency maintenance Even if you use gentle phonatory onset and airflow management, emphasize slow normal speech; if you use all three, teach one target skill at a time; refer to the preceding program for steps involved in implementing the optional airflow management and gentle phonatory onset; model more frequently and use simple language with younger children Model rate reduction through syllable prolongation; use a rubber band to show stretching of syllables; use hand gestures to slow speech; use any other means the child will comprehend; model more frequently than you would for older children and adults; reduce your own rate; if selected, add rate reduction to airflow management and gentle phonatory onset; do not use DAF with very young children • begin at the word level

3. A Simplified, Minimal Therapy for Very Young Children (2- to 5-Year-Olds): An Exclusive Fluency Reinforcement Program
S
Treatment of stuttering in very young children can be simplified greatly; there is evidence that systematic positive reinforcement for fluency in very young children may be just as effective as any other procedure; in many cases fluency shaping that involves such skills as syllable prolongation and airflow management can be avoided; an advantage of an exclusive fluency reinforcement program (nothing else is used) is that the parents may be trained more easily to use the technique at home than perhaps any other method; another advantage is that the procedure does not negatively affect the prosodic features of speech; follow the steps outlined here to use a straightforward fluency reinforcement program; see the following entry to combine fluency reinforcement with direct stuttering reduction strategy. ● Make a thorough assessment of stuttering in the child; see the cited sources and the PGASLP ● Explain the method to the parents and recruit them to do treatment at home at least three times a week; each session should last 15 to 20 minutes ● Baserate dysfluencies for at least three consecutive sessions; offer treatment only if stuttering does not show systematic decline over baserate sessions • hold play-oriented conversational speech sessions and tape-record the sample • count all dysfluencies and the number of words spoken • calculate the percent dysfluency rates 462

• do not treat if the dysfluency rates show consistent decline over the three sessions; counsel the parents to return to clinic if the child shows an increase in the frequency of dysfluencies • note that a few children may show such decline and recover without formal treatment Begin treatment in conversational speech mode only, although the child’s utterances may be words, phrases, or short sentences Select stimulus materials the child likes; toys, arranged play situations, big, colorful picture, storybooks with attractive pictures, and so forth; consult the parents before selecting the materials; if practical, ask parents to bring the child’s favorite toys and storybooks to the treatment sessions Ask the parents to observe the first few treatment sessions and then have them join you and the child Evoke speech from the child in a play-oriented format; use the toys, pictures, and other materials to stimulate speech • show a picture and ask the child such general questions as ‘‘What do you see here?’’ and ‘‘What is happening here?’’ • show a picture and ask such specific questions as ‘‘What is the boy doing here?’’ ‘‘What is the girl eating here?’’ ‘‘What is this Mommy doing?’’ ‘‘What is the kitty doing here?’’ and so forth • tell a short story about a picture and ask the child to retell it • ask the child to tell you a story • let the child engage in controlled play and ask questions about what he or she is doing • comment on what the child is doing to stimulate speech • role play such situations as cooking or shopping to stimulate speech from the child 463

• use hand puppets and carry on a conversation that is appropriate to the characters • build simple blocks with the child and pretend difficulty on your part and ask questions about how to do it • give slightly more difficult block designs to stimulate questions and requests for help • show an array of toys placed on a high shelf and ask the child to describe them and request specific items • use your imagination to provoke speech in the context of play and story telling but do not allow the child to get lost in play ● Manage a behavioral contingency as you evoke speech in the play-oriented treatment sessions • positively reinforce the child for all fluent productions, be they single word productions, phrases, or short or long sentences • use verbal praise as the main reinforcer (‘‘That was nice speech’’; ‘‘That was not bumpy! It was smooth’’; ‘‘I like the way you talk.’’) • ignore all stutterings completely • if verbal praise is not effective, begin a token reinforcement program; give a token for every fluent production to begin with; use a fixed ratio schedule in which progressively more fluent responses are required to earn a token; exchange the token for a small gift of child’s choice at the end of the session • train parents in reinforcing the child for fluent productions • ask the parents to hold informal treatment sessions at home • ask the parents to submit a tape-recorded sample of home treatment sessions • go over the tape and fine-tune the parents’ skill in immediately and positively reinforcing fluent productions and to completely ignore stuttering 464
Stuttering: Combined Treatment • measure stuttering as described in the previous section • vary the treatment as found appropriate in light of treatment data • dismiss the child from therapy when the child has sustained fluency at 95% or better in conversational speech produced in naturalistic settings over at least a 3- week period • tell the parents to contact you if there is an increase in stuttering • give them a follow-up schedule and conduct followup assessments • if the dysfluency rate is below 5% during any assessment session, schedule booster treatment sessions
4. Fluency Reinforcement Program Combined With Direct Stuttering Reduction Methods. In treating children who stutter, the effects of positive reinforcement for fluency may be enhanced by adding an optional direct stuttering reduction program (nonexclusion time-out, called here pause-and-talk or response cost); to do this, take the following steps. ● Use all procedures described under the previous entry, An Exclusive Fluency Reinforcement Program ● Note that the fluency reinforcement program requires you to react only to fluent productions (with positive consequences) but nothing is done when the child exhibits a stutter; in this combined procedure, a direct stuttering reduction procedure is added to fluency reinforcement Add Response Cost to Fluency Reinforcement. Response Cost is a procedure to reduce an undesirable response directly; this procedure includes giving the child a token for every fluent production and removing a token contingent on every stuttering; thus, the procedure is a combination of fluency reinforcement and reinforcement withdrawal (corrective feedback or operant punishment) contingent on stuttering; there is evidence that this is an effective procedure. 465

structure the treatment session as described under the previous entry on An Exclusive Fluency Reinforcement Program ● Use practically all procedures described in the previous entry; except that to reinforce fluency, adopt a token system; explain the procedure to the child and the parents ● Design a token system; select plastic tokens to be used as reinforcers; assemble a variety of back-up reinforcers; note that tokens themselves are not the true reinforcers—the back-ups are. • consult with parents and the child in selecting back-up reinforcers • select small toys, stickers, other inexpensive gift items such as pencils, balloons, and crayons • note that the most effective back-up reinforcers for many children might be activities, not gift items • arrange opportunities to engage in such activities as listening to a story that you read, drawing on the chalkboard, a play activity that the child selects, and listening to taped music ● Give the tokens to reinforce fluent productions • at the beginning of the session, ask the child to select one tangible reinforcer he or she will get at the end of the session in exchange for the tokens; make sure you offer only those choices that you have access to • evoke conversational speech (as described in the previous entry) and give the child a token for every fluent production; continue to use verbal praise as in the previous entry • make sure the child is able to accumulate enough tokens at the end of the session; if necessary, give 466
Stuttering: Combined Treatment two tokens for every fluent production; this may be necessary if the child’s stuttering rate is very high and opportunities for earning the tokens are somewhat limited • at the end of the session, exchange the token for the selected reinforcer (e.g., a sticker or a pencil) • alternatively, give back-up reinforcers throughout the session if that is feasible (e.g., after every 5 minutes of work or as soon as the child accumulates a certain number of tokens required to earn the back-up reinforcer, take a break for 1 or 2 minutes and allow the child to draw, listen to part of a story, listen to music, etc.); promptly terminate the activity and return the child to conversational speech and fluency monitoring ● Withdraw tokens to directly reduce stuttering while increasing fluency with reinforcement • explain this aspect of treatment to the child; inform him or her that you will be taking away a token for every instance of stuttering or bumpy speech • model a stutter and immediately remove a token from your own pile to demonstrate the procedure to the child • tell the child that his or her goal is to keep as many tokens as possible so as to earn a gift or an activity and not to lose the tokens to stuttering and thus lose the gift or the activity • watch for the earliest sign of a dysfluency or stutter (a lip puckering, an increased tension anywhere in the facial region, the beginnings of a sound prolongation or a sound repetition, twitching of the eyebrow) • as soon as a sign of stuttering or stuttering itself appears, take away a token the child has accumulated by producing fluent speech 467

Pauseand-talk is a procedure to directly reduce an undesirable response; more often described as time-out; because of variations in time-out procedures and some common misapplications of them, a more descriptive pause-and-talk is preferred here; there is evidence that pause-and-talk is an effective procedure to reducing stuttering without affecting the natural prosodic features of speech; pause-and-talk can easily be combined with positive reinforcement for fluency. ● Describe the procedure to the child and point out its effectiveness ● Baserate stuttering, select stimulus materials, and structure the treatment session as described under An Exclusive Fluency Reinforcement Program ● Use all procedures described under An Exclusive Fluency Reinforcement Program in the previous en468
Stuttering: Combined Treatment try; as described, reinforce fluent productions with verbal praise ● Add pause-and-talk to fluency reinforcement • continue to engage the client in conversational speech and to reinforce fluent productions with verbal praise • at the earliest sign of a stutter, say ‘‘Stop,’’ turn your face away to avoid eye contact with the client, and freeze for 5 seconds; you may look at your watch to count 5 seconds • at the end of the pause (time-out) duration, look at the client to re-establish eye contact, smile, and say something that will let the client continue talking (e.g., ‘‘You can talk now’’; ‘‘You were saying . . .’’; ‘‘OK’’; etc.); note that soon the client will begin talking again as soon as you re-establish your eye contact • make sure that the client completely ceases talking when you say ‘‘Stop’’; the method is ineffective if the client continues to talk even though you have terminated eye contact and have turned away ● Continue the procedure until fluency is stabilized in conversational speech in natural settings • measure stuttering in all sessions as describe in the previous entry • probe fluency and stuttering periodically as described in the previous entry • periodically probe the speech rate to make sure that the client is sustaining fluency without a rate change that affects prosodic features; available evidence suggests that the rate is not negatively affected and may even increase slightly when stutterings decrease • train parents to conduct home treatment sessions • monitor the home treatment sessions with taped samples and refine the parents’ skills in administering the treatment 469

5. Direct Stuttering Reduction Procedures Combined With Fluency Shaping Techniques. A novel
S
approach to treating stuttering in which fluency shaping techniques are combined with direct stuttering reduction methods; may be the most suitable for certain clients with whom pause-and-talk or response cost may not produce the maximal effects partly because of excessive frequency of stuttering; involves only a minimal use of fluency shaping (minimal syllable prolongation, only of the initial syllable of the first word of an utterance); thus it avoids the negative side-effects of fluency shaping (excessively slow and monotonous speech); although minimal prolongation may not be effective in itself, it may be effective when combined with pause-and-talk or response cost; experimental evidence is emerging in its favor; note that this technique may be used with adults or older children who stutter; this procedure may be unnecessary for very young children (3- to 5-year-olds) who may benefit the most from An Exclusive Fluency Reinforcement Program, described earlier under #3. ● Assess the client’s stuttering thoroughly; determine the forms and frequency of dysfluencies in conversational speech in clinical and extraclinical situations; consult the cited sources and the PGASLP ● Select a combination of a minimal syllable prolongation (MSP) with either pause-and-talk (P-&-T) or response cost (RC); possibly, a child will react better to one combination (e.g., MSP plus RC) than to the other (e.g., MSP plus P-&-T); therefore, be prepared to experiment ● Describe the procedure to the client and the family; tell them you will be using a slight syllable prolongation with either RC or P-&-T and that you will be initially trying both the combinations to select the one that works best with the child 470
Stuttering: Combined Treatment ● Engage the child in conversation within a play-oriented,
semistructured situation; see An Exclusive Fluency Reinforcement Program under #3 for details on structuring play-oriented treatment sessions with young children ● Apply the MSP plus P-&-T combination; begin with MSP (it does not matter what combination you try first; your preference for either RC or P-&-T may influence your initial selection) • model a slight prolongation of the initial syllable of the first word in an utterance; do not prolong all the syllables of all the words as it is done in the fullfledged fluency shaping technique • ask the child to imitate your production; make sure the child imitates a slight prolongation of the initial syllable of the first word only • reinforce the child for correct prolongation with verbal praise or with a token backed up with other reinforcers • simultaneously, every time the child stutters or you observe an earliest sign of a stutter, say ‘‘Stop,’’ turn your face away from the client, freeze, look at your watch for 5 seconds • make sure the client ceases talking • re-establish the eye contact, smile, and indicate in some way that the client can now resume talking (e.g., say ‘‘You can talk now,’’ ‘‘You were saying . . .,’’ ‘‘OK’’; etc.); note that after a few trials of this kind, most client will resume their speech as soon as you re-establish your eye contact and smile • after a few successful imitations of MSP, drop modeling and prompt the syllable prolongation by a hand signal; continue to apply P-&-T for all stutterings; client now is talking with MSP and pausing after each stuttering • continue this for two or three sessions to evaluate the effects of this combined procedure 471

• measure the exact frequency of all dysfluencies and the number of words spoken; calculate the percent dysfluency rate for all sessions so you can later compare the effect of this combination with that of the other • do not try the other combination and continue with this combination only if the changes are impressive, consistent, and the client seems happy with the technique (smiling and cooperative in the sessions and eager to work with you) with no signs of stress or negative reactions to the procedure • try the other combination if you do not find the results impressive (reductions in stuttering are minimal, the client does not seem to enjoy the session, is reluctant to work with you, the client is not punctual to the sessions, or even misses them) • note that tokens, exchanged for backup reinforcers, may be used to reinforce fluent productions; but do not withdraw a token for dysfluent productions, as this would be response cost; in this MSP and P-&-T combination, consequate dysfluent productions only with P-&-T ● Try the MSP plus RC combination (this could very well be the first combination you try); note that RC involves reinforcing fluent productions with a token backed up by other reinforcers and removing a token for every dysfluent productions ● Assess the client’s stuttering thoroughly; determine the forms and frequency of dysfluencies in conversational speech in clinical and extraclinical situations; consult the cited sources and the PGASLP ● Describe the procedure to the client and the family; tell them you will be using a slight syllable prolongation with RC (or P-&-T if you already have tried the RC combination); tell them that you will select the one that works best with the child

Stuttering: Combined Treatment ● Engage the child in conversation within a play-oriented,
semistructured situation; see An Exclusive Fluency Reinforcement Program under #3 for details on structuring play-oriented treatment sessions with young children ● Apply the MSP plus RC combination; begin with MSP • model a slight prolongation of the initial syllable of the first word in an utterance; do not prolong all the syllables of all the words the way it is done in the fullfledged fluency shaping technique • ask the child to imitate your production; make sure the child imitates a slight prolongation of the initial syllable of the first word only • reinforce the child for correct prolongation resulting in stutter-free speech with a token the child will later exchange for a backup reinforcer • simultaneously, every time the child stutters or you observe an earliest sign of a stutter, withdraw a token from the child (this is the response cost aspect of the combination) • continue this MSP, token presentation for fluent productions, and token withdrawal for stuttering for two or three sessions to evaluate the effects of this combined procedure • if unsure of the effects, administer for another session or two • measure the exact frequency of all dysfluencies and the number of words spoken; calculate the percent dysfluency rate for all sessions so you can later compare the effect of this combination with that of the other • compare the rate of stuttering in treatment sessions involving MSP plus P-&-T that you have already tried and MSP plus RC • pick the combination that reduced stuttering faster compared to the other combination

• consider other factors that may be important in treatment technique selection: client’s intense dislike of the technique, uncooperative behavior during treatment sessions in spite of good treatment effects, poor treatment attendance that may be attributable to a dislike of treatment, and strong parental objection in spite of positive effects and a good effort to convince them; in such cases, use an alternative, which may be the other combination as long it is effective (even if not to the same extent as the just applied procedure); note that the alternative my be a positive reinforcement of fluency, fluency shaping with syllable prolongation and airflow management, or any other techniques described in this section on Stuttering • tell the client and the family about the combination (or other technique) you have picked; explain why you picked that combination by showing the data demonstrating greater or faster reduction in stuttering • if selected (because of its more impressive effects compared with the other combination, client satisfaction with the technique as indexed by smiling and cooperativeness in the sessions and an eagerness to work with you with no signs of stress or negative reactions to the procedure), continue with the MSP plus RC combination until fluency is stabilized in the clinic and in natural settings • if MSP plus RC is not selected, continue with the technique selected (may be the other combination or a different technique altogether) • dismiss the client when fluency is sustained in the treatment setting as well as in the client’s natural setting • arrange for follow-ups and booster treatment sessions Ahlander, E., & Hegde, M.

Treatment of Stuttering: Specific Techniques or Programs Airflow Management in Stuttering Treatment. Regulated airflow used in the treatment of stuttering; also called Regulated Breathing; a component in many stuttering treatment procedures; effective in inducing stutter-free speech; supported by clinical research; often combined with other treatment targets including Gentle Phonatory Onset and Prolonged Speech (described later in this section). ● Preferably, combine it with prolonged speech and gentle phonatory onset ● Model Regulated Breathing to produce stutter-free speech • take an inhalation through the nose, slightly deeper than the usual so it is easily observed • exhale a small amount of air through the mouth before initiating phonation • initiate phonation slowly, gently, and softly only after the start of exhalation • model the production of single words or phrases • prolong the vowels and reduce the rate ● Ask the client to imitate your modeled productions ● Reinforce the imitative productions ● Model frequently and stabilize regulated breathing of inhalation and slight prevoice exhalation ● Fade modeling and evoke regulated breathing and speech production
475
S
Stuttering Treatment: Specific Programs ● Move through the sequence of words, phrases, and
S
sentences as you add other components (soft and gentle phonatory onset, prolongation of vowels, and slow rate of speech) ● Fade the explicit management of airflow into a more natural use of airflow to sustain fluency in conversational speech in and out of the clinic ● Reinstate regulated breathing throughout the treatment when found necessary Continuous Airflow. Maintaining airflow throughout an utterance; typically used in conjunction with such other treatment targets as exhalation, slight inhalation before phonation and rate reduction; helps induce stutter-free speech. ● Instruct the client to take enough air before beginning speech production ● Ask the client to exhale a slight amount of air before initiating phonation ● Ask the client to initiate phonation gently and softly ● Ask the client to maintain an even airflow throughout an utterance ● Model the technique ● Reinforce the client for correct production of the target behavior Continuous Phonation. Maintaining phonation throughout an utterance; a stuttering treatment target; often combined with Gentle Phonatory Onset, Airflow Management, and Prolonged Speech (all described in this section). ● Instruct the client in maintaining phonation throughout an utterance ● Model continuous phonation in such a way as to blur the word boundaries ● Ask the client to imitate your modeling ● Reinforce correctly imitated productions
476
Stuttering Treatment: Specific Programs ● Begin with shorter phrases and progress to longer
sentences
● Combine it with other targets, including syllable
prolongation, gentle phonatory onset, and airflow management Counseling as Treatment for Stuttering. A collection of varied approaches to treating stuttering by giving information, advice, and strategies to deal with the problem; a range of techniques most of them psychologically oriented; recipients are parents of children who stutter and adults who stutter; often combined with direct methods of treating stuttering; efficacy of counseling when used exclusively with no direct work with stuttering by either the clinician or the parent is not established; when combined with direct work on stuttering, whether counseling had any effect is unclear. Counseling Parents of Children Who Stutter. Using the psychological methods of counseling to indirectly treat stuttering in their children; an Indirect Stuttering Treatment method (described later in this section); the main approach is talking with the child’s parents to change their feelings, attitudes, ideas, and expectations about stuttering and fluency; efficacy of this approach not established; often combined with Direct Stuttering Treatment (described later in this section). ● Be a sensitive, uncritical, accepting listener ● Find out what the parents wish to accomplish through counseling ● Let the parents explore their feelings, emotions, perceptions, and expectations relative to their child’s stuttering ● Let the parents freely talk about their fears, possible feelings of guilt, and their overt reactions to stuttering in their child
477
S
Stuttering Treatment: Specific Programs ● Let the parents talk about their strategies of deal-

fering professional views and ideas they may not have known or considered ● Express approval of their positive feelings and helpful reactions toward their child ● Help them realize their child’s strengths and limitations ● Reduce their negative thoughts and feelings, including potential feelings of guilt by reassuring them that they may not have created the problem ● Let the parents put their child’s stuttering in perspective so that they do not exaggerate its negative effects ● Let the parents realize that no child is fluent all the time ● Explore actions the parents may have taken with positive effects on the child’s fluency and encourage them to increase or strengthen them ● Explore actions the parents may have taken that have worsened the child’s problems and encourage them to eliminate or reduce them ● Explore the parents’ ideas about fluency and stuttering to encourage a more realistic view of them ● Discuss the kinds of communicative demands the parents make and ask them to reduce such demands ● Encourage the parents to create more positive speech experiences for the child by withholding criticism and accepting the child’s stuttered attempts at communication Counseling Persons Who Stutter. Using psychological methods of counseling to indirectly treat persons who stutter; an Indirect Stuttering Treatment (described later in this section); the main approach is 478
Stuttering Treatment: Specific Programs talking with the client to change feelings, attitudes, and expectations; efficacy of this approach is not established; often combined with Direct Stuttering Treatment (described later in this section). ● Be a sensitive, uncritical, accepting listener ● Find out what the client wishes to accomplish through counseling ● Let the client explore his or her feelings, emotions, perceptions, and expectations relative to stuttering ● Let the client talk about the difficult speaking situations, listener reactions, and his or her own emotional reactions ● Help the client find his or her own solutions by offering professional views and ideas the client may be unaware of or may not have considered ● Discuss the client’s strengths that he or she may not have realized ● Reduce negative thoughts and feelings by having the client concentrate on positive experiences, including positive speech experiences ● Let the client put stuttering in perspective so that he or she does not exaggerate its negative effects ● Let the client realize that no one is fluent all the time ● Explore actions the client takes that may exacerbate stuttering and encourage the client to eliminate or reduce them ● Explore actions and situations that enhance fluency and encourage the client to increase them or strengthen them ● Encourage the client to talk more positively about himself or herself Delayed Auditory Feedback (DAF).

speech; used in treating persons who stutter and those who clutter to slow their speech rate; reduces or eliminates stuttering, but induces unnatural sounding speech; a widely used stuttering treatment technique; a component in many programmed or comprehensive treatment approaches; useful in establishing StutterFree Speech (described later in this section) but needs additional procedures to make the speech sound natural and to make the fluency last over time and across situations. ● Assess the client thoroughly and establish baserates of stuttering and the speech rate ● Select a miniaturized, electronic feedback devise that the client can use in most situations ● Ask the client to wear the portable device (may use a desk-top unit with a loss in flexibility) ● Experiment with different delays to set a clientspecific delay that induces stutter-free speech (most clients are stutter-free at 250 milliseconds of delay) ● Begin by asking the client to respond to questions that evoke two- or three-word phrases or short sentences ● Drop down to word level only if the client cannot maintain stutter-free speech at the phrase or shortsentence level ● Model slow, prolonged speech if necessary ● Use oral reading to stabilize a slow, prolonged production if necessary (some initially find oral reading under DAF easier than speaking) ● Establish stutter-free speech with the initial delay over a few sessions ● Increase the length of utterances gradually ● Move to more spontaneous conversational speech containing longer and more complex utterances ● Fade the DAF by initially decreasing the delay in gradual steps; reduce it in 50-millisecond intervals 480
Stuttering Treatment: Specific Programs or other intervals that still help maintain stutter-free speech ● Reduce the intensity of DAF ● Increase the rate of speech while still maintaining stutter-free speech; reinforce the client for speaking at progressively faster rates ● Eliminate the delay altogether, but let the client wear the unit ● Increase the rate further to move it closer to the pretreatment, judged normal, or natural sounding rate ● Shape the normal prosodic features including normal rhythm, intonation, intensity variations, emotional connotations, and so forth ● Conduct informal treatment sessions in varied nonclinical settings ● Train family members, teachers, and others to reinforce fluent, natural sounding speech in nonclinical settings ● Teach Self-Control (Self-Monitoring) skills (charting one’s own stuttering, stopping soon after a stuttering or at the earliest sign of increased rate) ● Dismiss only after a natural sounding fluent speech is established ● Counsel the client about the possibility of relapse and the need for Booster Treatment ● Follow up and arrange for booster treatment (relapses are common; follow-up and booster treatment are critical in maintenance) Direct Stuttering Reduction Strategy: Pause-and-Talk (Time-Out). A brief period of nonreinforcement during which the client stops talking and the clinician avoids eye contact with the client; the period is imposed at the earliest sign of an imminent stuttering or associated behaviors or immediately following those behaviors; duration typically does not exceed 10 seconds; effective in reducing stuttering; supported by 481

controlled experimental evidence; has the advantage of not inducing an artificial and unacceptable pattern of fluency; especially effective with children. ● Assess the client thoroughly and baserate stuttering, dysfluencies, as defined ● Use pictures, objects, storybooks, and toys to evoke continuous speech from young children, ● Use topic cards initially to promote extended monologues from adults ● Introduce natural conversation with both adults and children as soon as practical ● Instruct the client about the procedure: ‘‘I will be saying ‘Stop’ at the earliest sign of stuttering. I want you to stop talking immediately. I will also look away from you and count to five seconds. I will then look at you again. When I look at you, continue talking.’’ ● Ask the child to state the rule and repeat the instructions if necessary ● At the earliest sign of stuttering, say ‘‘Stop,’’ look away for 5 seconds, and then reestablish eye contact ● If the client does not begin talking immediately, prompt verbally or nonverbally (e.g., ‘‘You were telling me’’; ‘‘Yes, continue’’; a hand gesture to continue) ● Stop the client for every instance of stuttering or dysfluencies; be prompt, forceful, and unambiguous in your feedback ● Ensure that the client does stop talking when you say so ● Watch for undue emotional responses; they tend to disappear; however, if they persist, switch to another procedure ● Measure the frequency of stutterings or dysfluencies as you have defined them in each session or after the session through tape-recorded samples
482
Stuttering Treatment: Specific Programs ● Begin with words and phrases and progress to con-
trolled sentences and natural conversational speech
● Teach Self-Control (Self-Monitoring) skills in which
the client measures and records his or her stutterings and learns to pause at the earliest sign of stuttering (self-imposed time-out) ● Train family members, teachers, siblings, friends, and others to give subtle signals for the client to stop when they observe stuttering in all situations ● Fade time-out and keep the client on social, verbal reinforcers for fluency ● Shift treatment to naturalistic settings; give unobtrusive feedback to the client in such settings ● Train parents or spouses to hold informal training sessions at home; let them use time-out initially for stuttering and only verbal praise for fluency later ● Have the client or the family members submit taperecorded home conversational speech samples for your analysis of stuttering frequency ● Dismiss the client only when the rate of dysfluencies is below the set criterion (e.g., less than 3%) ● Counsel the client, the family members, or both about possible relapse of stuttering and the need for booster treatment; ask the client to contact you as soon as stuttering increases ● Follow up the client and arrange for booster treatment Direct Stuttering Reduction Strategy: Response Cost. Withdrawal of a positive reinforcer made contingent on stuttering; each stuttering costs the client a reinforcer he or she has access to; effective in reducing stuttering; supported by controlled experimental evidence; especially applicable with children; does not induce an artificial pattern of fluency that should be faded out. ● Assess the client thoroughly and establish baserates of stuttering or dysfluencies, as defined

you a token for every word (later phrases and sentences) you speak without stuttering. At the end of the session, you can exchange the tokens for this gift here. You should have at least five tokens (or any such low number that ensures the gift for the child ) at the end of the session. The main thing is that I will take a token away from you every time you stutter. You should try to keep as many tokens as possible by speaking without stuttering.’’ Ask the child to state the rule and repeat the instructions if necessary Reinforce initially for every fluently spoken word; progress to phrases, controlled sentences, and conversational speech Take a token away promptly and in a matter-of-fact manner immediately following a stuttering or at the earliest sign of it Watch for undue emotional responses at token loss; they tend to disappear; however, if they persist, switch to another procedure Measure the frequency of stutterings or dysfluencies as you have defined them in each session or after the session through tape-recorded samples Teach Self-Control (Self-Monitoring) skills in which the client measures and records his or her stutterings and learns to hand you a token at the earliest sign of stuttering (self-imposed response-cost) Fade response cost and keep the client on social, verbal reinforcers for fluency 484
Stuttering Treatment: Specific Programs ● Train family members, teachers, siblings, friends,
and others to give subtle signals for the client to stop when they observe stuttering in all situations ● Shift treatment to naturalistic settings; give unobtrusive feedback to the client in such settings ● Train parents or spouses to hold informal training sessions; let them initially use your token system; later let them fade the tokens and use only verbal praise ● Have the client or the family members submit taperecorded home conversational speech samples for your analysis of stuttering frequency ● Dismiss the client only when the rate of dysfluencies is below the set criterion (e.g., less than 3%) ● Counsel the client, family members, or both about possible relapse of stuttering and the need for booster treatment; ask the client to contact you as soon as there is an increase in stuttering ● Follow up the client and arrange for booster treatment Direct Stuttering Treatment. Methods in which the clinician concentrates on reducing stuttering in the client as against trying to indirectly reduce it through counseling and other methods; in behavioral treatment, includes Direct Stuttering Reduction Strategy: Pauseand-Talk (Time-Out) and Direct Stuttering Reduction Strategy: Response Cost (described earlier in this section); a contingency is imposed on stuttering itself, contrasted with counseling parents of stuttering children or stuttering adults. Fluency Reinforcement Techniques. Techniques of stuttering treatment in which durations of fluency or fluent utterances of varied lengths are positively reinforced; may be used exclusively, in which case, there is no contingency on rate reduction, airflow management, or other targets; may be more effective with younger children than with older children or adults; when not effective, other targets added. 485

which toys, objects, picture books, and storybooks serve as stimuli ● Evoke controlled conversational speech in a relaxed, play-oriented manner ● Select a duration-based (e.g., fluent speech sustained for 20 seconds) or topographically based (e.g., a word, phrase, or a sentence) fluency responses for reinforcement ● Describe and model fluent utterances for the child; describe and model dysfluent utterances as well ● Describe the contingency in simple terms (e.g., ‘‘I will give you a token for easy speech.’’) ● Evoke controlled, limited utterances; use modeling ● Reinforce promptly and generously for fluent utterances or durations ● Ignore stuttering ● Increase the length of utterances or duration of utterances in gradual steps ● Train at the level of conversational speech ● Shift training to nonclinical settings ● Train parents in similar techniques and ask them to conduct home treatment sessions ● Counsel parents about the possibility of relapse and the need for booster treatment ● Follow up and arrange for booster treatment Fluency Shaping Techniques. A collection of somewhat varied treatment procedures for stuttering with an emphasis on teaching skills of fluency; contrasted with the Fluent Stuttering (described in this section) approach of Van Riper; the goal is natural-sounding normal fluency in everyday situations sustained over time; children are more likely to achieve this goal than adults; most adult stutterers may realize only controlled 486
Stuttering Treatment: Specific Programs (monitored) fluency; include Fluency Reinforcement Techniques, Delayed Auditory Feedback, Regulated Breathing or Airflow Management, Gentle Phonatory Onset, Rate Reduction, and Prolonged Speech (all described in this section); little or no attention paid to feelings and attitudes; emphasis on programmed instruction and objective data collection; to use a comprehensive fluency shaping procedure that includes airflow management, gentle phonatory onset, and syllable prolongation, see at the beginning of the main entry Stuttering, and follow the procedures described under 1. A Contemporary, Comprehensive Treatment Procedure for Stuttering in Older Children and Adults. Fluent Stuttering: Van Riper’s Approach. An extensive, early, and influential treatment program for stuttering; also described as stuttering modification therapy; goal is to teach less abnormal, socially more acceptable stuttering, not necessarily normal fluency; contrasted with Fluency Shaping Techniques (described in this section); includes counseling and psychotherapy to change feelings and attitudes. ● Teach stuttering identification • teach the client to identify his or her stuttering and all associated problems including negative feelings, avoidance, word fears, and easy and difficult stutterings, with discussion, demonstration, reading, modeling, and so forth • teach the stutterer to identify his or her stuttering and associated problems in everyday speaking situations ● Desensitize to toughen the client to his or her stuttering • encourage the stutterer to be open and honest with his or her stuttering • ask the stutterer to freeze stuttering; teach the client to continue stuttering until told to stop 487

Gentle Phonatory Onset. Soft, easy, slow, and relaxed initiation of sounds as against harsh, abrupt, and tensed, initiation; a target behavior in the treatment of stuttering; often combined with such other target behaviors as Airflow Management, Prolonged Speech, or Rate Reduction (described in this section). ● Combine it with prolonged speech, airflow management, or both because gentle onset alone is not a sufficient treatment target ● Instruct the client on the need for gentle phonatory onset; contrast it with its opposite; point out the relationship between abrupt onset and stuttering ● Demonstrate (model) gentle and tensed/abrupt onset and show how speech may be dysfluent with the latter ● Ask the client to initiate sound softly, gently, with a relaxed posture ● Model soft and easy initiation of some vowels ● Ask the client to imitate and reinforce correct imitative productions ● Model soft articulatory contacts for consonants and relaxed production in general ● Reinforce imitative productions of soft articulatory contacts and relaxed speech production ● Model a few single-syllable words (e.g., I, bye, Hi ) with soft and slow onset and ask the client to imitate ● Reinforce correct imitative productions of singlesyllable words ● Ask the client to produce selected simple words and phrases with gentle onset (evoked, not modeled) ● Add airflow management, prolonged speech, or both to gentle onset

One of two highly structured and programmed operant treatment approaches of the Monterey Fluency Program (described later in this section); developed and researched by B. Ryan and B. Van Kirk; involves reinforcing fluent speech starting with single-word productions and ending with conversational speech; the length and complexity of utterances are increased gradually in the intermediate steps; supported by clinical evidence. Indirect Stuttering Treatment. Methods in which the clinician tries to manage stuttering in the client without concentrating on reducing stuttering directly; includes Counseling as Treatment for Stuttering (described earlier in this section); there is no direct work on reducing stuttering. Integration of Stuttering Modification and Fluency Shaping. A dual approach that uses both the Stuttering Modification and Fluency Shaping Techniques (both described in this section); a procedure of treatment developed by T. Peters and B. Guitar; the dual approach is more forcefully applied to advanced stutterers than to beginning stutterers; uses a variety of handouts (e.g., understanding stuttering, how to be open about stuttering, and how to use feared words) during treatment sessions. ● Let the client understand his or her stuttering • be warm and friendly; describe the treatment program to the client • ask the client to read a brief description of stuttering, what it is, and how it develops; use the authors’ handout ‘‘Understanding Your Stuttering’’; answer all questions; share and reinforce the client’s insights 490
Stuttering Treatment: Specific Programs • catalog all aspects of the client’s stuttering to give a good understanding of the problem; model stuttering, use videotapes or mirrors to demonstrate stuttering ● Reduce negative feelings and attitudes and eliminate avoidance behaviors • encourage the client to discuss his or her stuttering openly with family, friends, and acquaintances; use the authors’ handout ‘‘Discussing Stuttering Openly’’ in the treatment session • ask the client to create a hierarchy of feared and avoided words and situations; encourage the client to use feared words and enter previously avoided speaking situations freely and frequently; use the authors’ handout ‘‘Using Feared Words and Entering Feared Situations’’ • teach the client the technique of freezing or holding onto the moment of stuttering; use the authors’ handout; when the client stutters, ask to continue (to repeat, prolong) until you signal to stop; teach the client to be calm while doing this • teach the client Voluntary Stuttering; use the authors’ handout ‘‘Using Voluntary Stuttering’’; explain the rationale for it; model brief, easy repetitions or prolongations for the client to imitate; take the client to naturalistic settings where the client will stutter voluntarily ● Teach fluency enhancing skills and modify the moments of stuttering • teach Rate Reduction in Treating Stuttering induced by DAF, Gentle Phonatory Onset (both described in this section) and Soft Articulatory Contacts; use the authors’ handout, ‘‘Using Fluency Enhancing Behaviors’’; fade DAF in gradual steps • stabilize fluency enhancing skills in conversational speech without DAF 491

I will say ‘Great talking’ when I hear smooth talking.’’ • train parents to evoke single words with the help of flash cards with a child whose stuttering is very severe; train parents to use more play-oriented conversational speech with a child whose stuttering is mild • train parents to decrease the treatment structure as the child becomes more fluent • train parents to praise the child for stutter-free speech with such verbal statements as ‘‘Good talking!’’ ‘‘Your speech sounds great!’’ or ‘‘Your words are smooth!’’ and so forth; train them to deliver such praise promptly, consistently, and with enthusiasm and sincerity; train them to supplement praise with such tangible reinforcers as stickers or tokens ● Train parents to react in one of several ways when their child stutters in structured treatment sessions at home: • ignore stuttering • say something like ‘‘That was a bumpy word’’ and continue conversation • model a fluent production of the stuttered word and continue conversation • say ‘‘A bumpy word occurred’’ and ask the child to repeat the word correctly or fluently • ask the child to repeat the stuttered word fluently and, if successful, ask the child to do that one or two more times; reinforce fluent productions
494
Stuttering Treatment: Specific Programs • watch for signs of distress in the child and postpone the use of correction if the child reacts emotionally to it; reintroduce correction gradually and after the child experienced success with reinforcement for stutter-free speech • deliver significantly fewer corrections than praise in all sessions ● Train parents to deliver treatment on-line • train parents to monitor speech in everyday speaking situations (e.g., the parents correct a child’s stuttering while shopping or on a playground) • initiate this step when the parent can measure and correct stuttering reliably and stuttering has begun to decrease as a result of treatment sessions conducted at home ● Train parents to teach their child self-monitoring skills by • periodically asking the child whether a production was smooth or bumpy to encourage selfevaluation • praising the child for self-correction of stuttered production ● Initiate a maintenance program when the child’s daily SR at home is 2.0 or lower and the clinic %SS is 1 or less for 3 consecutive weeks • decrease the frequency of clinic visits gradually, building such decreases as rewards for maintaining fluency at home • schedule maintenance clinic visits at 2 weeks, 2 weeks, 4 weeks, 4 weeks, 8 weeks, 8 weeks, 16 weeks, and 32 weeks • assess stuttering when they visit the clinic • advance the child to the next visit if the child maintains an SR average of 2.0 and SMST 1.0 or less

Metronome-Paced Speech. Speech that is regulated by the beats of a metronome; a form of treatment used for stuttering and cluttering; syllables or word initiations may be regulated; may be used to slow down or accelerate the rate of speech; documented immediate effects of reduced or eliminated stuttering, but timed, rhythmic, and unnatural sounding speech; research needed to document long-term effects; possibility of client adaptation to the beats (no more effective); Delayed Auditory Feedback (DAF) (described earlier in this section), with its similar effects, is preferred over metronome speech in the treatment of stuttering. ● Assess the client and baserate stuttering ● Select a miniaturized, battery-operated, electronic metronome the client can wear like a hearing aid ● Find the client-specific beat rate that reduces or eliminates stuttering ● Have the client time the production of syllables with the beats in the early stages of treatment ● Have the client time the production of words with the beats in the later stages ● Have the client time the production of phrases and sentences as fluency increases and stabilizes ● Increase the rate of beats or vice versa, depending on the starting point
496
Stuttering Treatment: Specific Programs ● Ask the client to initially wear the unit in all
situations
● Fade the metronome beats by reducing its intensity
in gradual steps
● Ask the client to wear the unit with the power
turned off

Monterey Fluency Program (MFP). A programmed operant approach to establish, transfer, and maintain fluency in persons who stutter; uses one of two specific methods: Delayed Auditory Feedback (DAF) and Gradual Increase in Length and Complexity of Utterances (GILCU); DAF is often used with older or more severe stutterers and GILCU is more frequently used with younger and less severe stutterers; contains establishment, transfer, and maintenance phases; supported by clinical evidence; developed and researched by B. Ryan and B. Van Kirk. MFP Delayed Auditory Feedback Method ● Give an overview of the program to the client, the parents, or both; describe the role the parents or other family members will play in fluency maintenance at home ● Give a criterion test consisting of 5 minutes of reading, monologue, and conversation to baserate stuttering; measure stuttering in terms of stuttered words per minute (SW/M) ● Implement the fluency establishment program

Prolonged Speech. Speech produced with extended duration of speech sounds, especially vowels, and particularly those in the initial position of words; a target behavior in stuttering treatment; not a treatment procedure but the effect of treatment; induces Stutter-Free Speech; results in fluency that sounds unnatural and socially unacceptable; useful in establishing stutter-free speech; often combined with such additional targets as Natural Sounding Fluency, Airflow Management, and Gentle Phonatory Onset; a common component in many contemporary stuttering treatment programs; supported by clinical evidence, some experimentally controlled; procedurally, either DAF-induced or clinician-induced. Prolonged Speech, DAF-Induced. Speech that is produced by prolonging speech sounds, especially the vowels, and particularly in the word-initial positions; prolongation of sounds forced by the Delayed Auditory Feedback (DAF); induces stutter-free speech that sounds fluent but unnatural and socially unacceptable; a target behavior in many stuttering treatment programs; often combined with such other targets as Airflow Management, Gentle Phonatory Onset, Normal Prosody and Natural-Sounding Fluency; supported by clinical evidence, some experimentally controlled; clinical procedures under Delayed Auditory Feedback. 501

Prolonged Speech, Clinician-Induced. Speech that is produced by prolonging speech sounds, especially the vowels, and particularly in the word-initial positions; prolongation of sounds taught by clinicians without mechanical help; Instructions, Modeling, and Differential Reinforcement are the most effective techniques to induce it; supported by clinical evidence, some experimentally controlled; induces stutter-free speech that sounds fluent but unnatural and socially unacceptable; a target behavior in many stuttering treatment programs; often combined with such other targets as Airflow Management, Gentle Phonatory Onset, Normal Prosody, or Natural-Sounding Fluency. ● Assess the client and baserate the stuttering rate and speech rate ● Instruct the client in producing prolonged speech and describe its need, effects, and justification ● Ask the client to prolong the vowels, especially those at the beginning of words, phrases, and grammatical clauses ● Ask the client to reduce the rate of speech throughout the utterance ● Model the prolonged speech and overall reduced speech rate ● Model words, phrases, and sentences to give the client an idea, but ask the client to imitate only what he or she can (perhaps only words); model frequently ● Reduce your own rate of speech and talk in a noticeably prolonged manner ● Reinforce the client’s prolonged speech promptly and lavishly ● Tell the client to ‘‘stop’’ (discontinue talking) at the earliest sign of increased rate, shortened vowels, or stuttering 502
Stuttering Treatment: Specific Programs ● Repeat modeling, especially in the early stages of
treatment whenever the client fails to maintain the target behaviors or produces stuttering ● Establish stutter-free (prolonged) speech at the topographic levels of words, phrases, sentences, and spontaneous conversational speech ● Use such performance criteria as 98 or 100% fluency at each topographic level, observed for a period of time or for a certain number of responses ● Increase the length of utterance as the client meets a particular performance criterion ● Decrease the extent of prolongation gradually as the client becomes more fluent ● Ask the client to increase the rate of speech and reinforce fluency at progressively increased speech rates ● Model normal prosodic features and ask the client to imitate ● Let the client slowly and gradually return to normal rate, rhythm, and prosody while maintaining fluency ● Train family members to signal the client to speak slowly and to reinforce fluent speech in daily situations ● Train the client in Self-Control (Self-Monitoring) skills by having him or her count stutterings ● Train the client to stop and slow down every time the rate increases or stuttering returns ● Conduct informal treatment sessions in varied nonclinical settings ● Counsel the client, the family, or both about the possibility of relapse and the need for booster treatment ● Follow up and arrange for booster treatment Rate Reduction in Treating Stuttering.

a typical target to reduce stuttering; a component of many treatment programs; similar to prolonged speech; supported by clinical evidence; may use Delayed Auditory Feedback to induce rate reduction; appropriate with very young children especially when the DAF is omitted. ● Establish the baserate of speech rate, measured in terms of syllables per minute or words per minute ● Instruct the client in rate reduction and describe its desirable effects ● Reassure the client that a more acceptable rate is the final target of treatment ● Reduce the rate by prolonging the vowels, not by increasing pause durations between words, phrases, and sentences ● Experiment with slower rates that reduce stuttering to near zero ● Model the effective rate selected for the client ● Ask the client to imitate the slower rate in producing multisyllable words and phrases by extending the duration of syllables (not pauses) ● Use delayed auditory feedback if instructions and modeling are not effective ● Shape slower rate in multisyllable words, phrases, sentences, and conversational speech to induce Stutter-Free Speech ● Fade the excessively slow rate of speech while the client maintains stutter-free conversational speech and moves toward more Natural Sounding Fluency ● Shape the normal or near-normal rate along with Normal Prosody ● Teach Self-Control (Self-Monitoring) of rate control that the client can use when needed in everyday situations Regulated Breathing. A direct stuttering reduction method in which the client is asked to modify 504
Stuttering Treatment: Specific Programs breathing patterns along with the use of such other strategies as thought formulation and relaxation; some clinical evidence supports its use but the effective component of the eclectic program is not clear; developed and researched by N. Azrin and his associates; only the components inhalation and slight exhalation before initiating phonation have been incorporated into several current treatment programs; more effective with older children and adults than with very young children. ● Ask the client to formulate thoughts before speaking ● Instruct the client to inhale and exhale a small amount of air before talking; model the target behaviors ● Ask the client to continue to exhale a little even after the last sound is produced ● Instruct the client to pause at natural speech junctures and formulate thoughts again ● Ask the client to stop soon after a stuttering occurs and relax, especially the chest muscles ● Ask the client to seek out previously avoided speaking situations ● Ask the client to practice the new method of speaking daily ● Train and ask the client to measure and record his or her stutterings in natural settings ● Train a family member in the procedure and let the person help the stutterer at home ● Maintain phone contact with the client to follow up Azrin, N.

Shadowing. A stuttering and cluttering treatment technique in which the client, without seeing the text, repeats (shadows) everything the clinician reads from a book; the client stays a few words behind the clinician; typical effect is to reduce the frequency of stuttering; popular in the 1960s and 1970s, especially in Europe; some clinician evidence suggests its effect in reducing stuttering; no research on maintenance of fluency. ● Assess the client and baserate the stuttering frequency ● Select a reading material that is suitable to the client ● Instruct the client to say everything that you read ● Give practice by reading a few sentences at a time, stopping, and reinstructing, if necessary ● Do not show the text to the client ● Read normally; do not change the rate, rhythm, or phrasing ● Tape-record the client’s shadowing to measure the frequency of stuttering during treatment sessions Stutter-Free Speech. Speech of a person who stutters that contains no or few stutterings; often not the same
508
Stuttering Treatment: Specific Programs as normally fluent speech because it may not sound natural when achieved by the use of Delayed Auditory Feedback, Rate Reduction, or Prolonged Speech induced by clinicians, and by Metronome-Paced Speech; a result of initial stages of such treatment methods; needs additional procedures to make the speech sound naturally fluent and make it last over time and across situations. Stutter-Free Speech: A Stuttering Treatment Program. A method of stuttering treatment developed and researched by G. Shames and C. Florance; uses Delayed Auditory Feedback (DAF) to induce slow, stutter-free speech; uses operant procedures to shape natural-sounding fluency. ● Teach volitional control over speech (slower rate and continuous phonation) • reduce the speech rate through DAF (initial delay of 250 msec) • train the client to produce 30 minutes of stutterfree conversational speech at progressively reduced delays of 200, 150, 100, and 50 msec to increase the speech rate • teach the client to stretch each word into the following word to produce continuous phonation ● Teach Self-Control (Self-Monitoring) and selfreinforcement • teach the client to self-monitor fluent and stuttered speech so that he or she deliberately produces an acceptable rate and continuous phonation • teach the client to evaluate his or her fluent and stuttered productions • teach the client to self-reinforce by talking without monitoring after a period of deliberately monitored speech ● Implement transfer and generalization procedures

Stuttering Modification. A collection of approaches to treating stuttering in which the emphasis is on changing the form of stuttering so that it is less severe and more socially and personally acceptable; the goal is not normal fluency, but less abnormality; approach exemplified by Fluent Stuttering approach of Van Riper (described earlier in this section); includes attempts to change attitudes and feelings; treatment sessions loosely structured; little emphasis on measurement of behaviors; contrasted with Fluency Shaping Techniques (described earlier in this section). Stuttering Prevention: A Clinical Method. An early treatment program for children who stutter; developed by W. Starkweather and his associates; based on the Demands and Capacities Model (DCM) of fluency and stuttering; goal is to reduce demands made on the child’s fluency and increase fluency capacities. 510
Stuttering Treatment: Specific Programs ● Assess the child’s capacity for fluency and the de-
mands the child faces
● Counsel the parents
• educate the parents about stuttering, the treatment program, and prognosis; give an optimistic outlook on improvement with treatment • change attitudes of parents by discussing their negative feelings and possible guilt • change behaviors of parents; ask them to speak at a slower rate; ask them to use shorter, simpler sentences while speaking to the child; let them know that negative reactions and punishment can worsen stuttering; encourage polite turn taking in conversation; ask them to arrange a special talking time with the child; ask parents to demand speech less often; teach parents the direct treatment techniques ● Modify directly the child’s stuttering and fluency • reduce the tension and struggle behaviors associated with dysfluency • initially, model behaviors (slower rate, less struggled word and phrase repetitions) without necessarily requiring the child to imitate them • later, ask the child to imitate slower rate by syllable prolongation • implement such fluency enhancing strategies as no interruption and no demands for verbal performance (silent periods are fine) • control play activities so that they are appropriate for the child’s cognitive level and allows for conversation ● Include direct intervention strategies and fluency shaping procedures as found necessary • use gentle phonatory onset and light articulatory contacts • time-out contingent on struggle behaviors • self-correcting 511

Subcortical Aphasia ● Promote a level of language use that is normal for
the child’s age and gender • model a level of language use that is appropriate for the child • change parent’s language as specified earlier ● Dismiss the child only when both the parents’ and the child’s behaviors have changed Starkweather, W., Gottwald, S. R., & Halfond, M. (1990). Stuttering prevention: A clinical method. Englewood Cliffs, NJ: Prentice-Hall.
Stuttering, Voluntary. A technique of stuttering modification in which the client is asked to stutter deliberately; the goal is to reduce the fear and embarrassment associated with it and to eliminate avoidance of stuttering; part of Van Riper’s Fluent Stuttering approach.
Subcortical Aphasia.
Aphasia presumably due to damage to subcortical structures, especially to basal ganglia and surrounding areas; somewhat controversial; to produce aphasia, subcortical damage must be extensive; some experts suspect that subcortical aphasia involves cortical damage as well; characterized by generally fluent speech, intact repetition, and articulation problems.
Submucous Cleft. Unexposed cleft of the hard palate, soft
S
palate, or both because of normal mucosal covering; speech in some cases may be hypernasal.
Substitution Processes.
A group of phonological processes in which one class of sounds is substituted for another; in phonological treatment, the target is to eliminate such processes; major substitution processes include: ● Deaffrication: substitution of a fricative for an affricate (e.g., a /t/, /s/, or a /k/ for /tʃ/; a /d/ or a /z/ for /d/) ● Denasalization: substitution of an oral consonant for a nasal consonant (e.g., /d/ for /n/) ● Gliding: substitution of a glide for a liquid (e.g., /w/ for /r/) ● Stopping: substitution of a stop for a fricative or an affricate (e.g., /p/ for /f/; /p/ for /v/, /t/ for /s/) 512
Super-Supraglottic Swallow ● Velar Fronting: substitution of an alveolar for a velar (e.g.,
/t/ for /k/, /d/ for /g/, /n/ for /ŋ/)
Super-Supraglottic Swallow. A swallowing maneuver that helps close the airway entrance before and during the swallow; it helps close the false vocal folds by tilting the arytenoid cartilage anteriorly to the base of the epiglottis before and during the swallow; arytenoids are tilted when the breath is held and the patient bears down; to implement this maneuver, ask the patient to: ● inhale and hold the breath tightly by bearing down ● swallow while holding the breath and bearing down
Supraglottic Swallow Maneuver. A procedure to reduce or control aspiration while modifying swallowing behavior during the oral phase of the swallow; teaches the client to voluntarily protect the airway. ● Ask the patient to inhale and hold the breath ● Place food in the mouth ● Ask the patient to tilt the head back and swallow ● Teach the patient to cough after each swallow to clear any residual food from the pharynx
Swallow Reflex. A series of reflexive actions needed to complete the swallow act; includes the reflexive elevation of the soft palate, closure of the airway, peristalsis (constriction of the pharyngeal constrictors), relaxation of the cricopharyngeal muscle to passage of food into the esophagus; often delayed in patients with dysphagia; may be triggered by stimulating the base of the anterior faucial arch.
Syndrome. A constellation of signs and symptoms that are associated with a morbid process.

TeflonTM or Collagen Injection TeflonTM or Collagen Injection. A medical treatment procedure for clients with paralyzed vocal folds; injected into the middle third of the fold, the two materials increase the bulk and the chances of abduction.
Terminal Response. The final response targeted in Shaping. Time-Out (TO). Time-out from positive reinforcement; also described as pause-and-talk as used in Stuttering treatment and in reducing a variety of undesirable behaviors; direct response reduction procedure in which one of the following three contingencies is placed on a behavior to be reduced: (1) a brief period of no reinforcement (nonexclusion TO); (2) exclusion of the person from the stream of activity (exclusion TO), but not from the current environment; or (3) removal of the person from the current environment and placing the person in an isolated place for a brief period (Isolation TO).
Exclusion TO
● Contingent on an undesirable response, exclude the client
from the current stream of activities, but not from the environment ● Let the client resume the activity at the end of the TO duration
Isolation TO
● Contingent on an undesirable response, remove the client
T
from the current environment
● Place the client in a specially designed situation for a cer-
tain duration
● Bring the client back to the normal environment at the end
of the TO duration
Nonexclusion TO
● Begin TO as soon as the client produces an undesirable
response
● During TO, do not interact with client ● Ask the client not to respond for the specified duration ● At the end of the TO duration, resume interaction
516
Tokens Tokens. Conditioned generalized reinforcers; objects that are earned during treatment and exchanged later for backup reinforcers. ● Always have back-up reinforcers the child can exchange the tokens for ● Let the child choose a back-up reinforcer in the beginning of each session ● Let the child understand the ratio of tokens to a back-up reinforcer ● Set a low ratio in the beginning and gradually raise the number of tokens needed to receive the back-up reinforcer
Tongue Thrust. A deviant swallow in which the tongue is pushed forward against the central incisors.
Topic Initiation.
A pragmatic language skill to initiate conversation on a topic; a frequent language intervention target; procedures described under Language Disorders in Children; Treatment of Language Disorders: Specific Techniques or Programs.
Topic Maintenance. A pragmatic language skill to maintain conversation for socially acceptable time periods; a frequent language intervention target; procedures described under Language Disorders in Children; Treatment of Language Disorders: Specific Techniques or Programs.
Topographic Sequence of Treatment. Sequencing treatment based on response complexity; most clients learn better if the target skills are simplified in the initial stages of therapy. ● Begin treatment with simpler topographic levels (words, phrases) and increase the topographic complexity in gradual steps (sentences, conversational speech) ● In treating articulation disorders, begin teaching a phoneme at the word or syllable level; as the client becomes proficient in producing the sound at this level, shift training to the phrase level; finally provide training in conversational speech 517
T
Topography ● In language therapy, teach grammatic morpheme in words
or phrases (e.g., cups or two cups); as the client becomes proficient in producing the morpheme at this level, shift training to sentences and conversational speech ● In fluency therapy, train such skills as gentle onset, prolonged speech, and airflow management initially in words and phrases and subsequently in sentences and conversational speech ● In voice therapy, use single vowel productions (e.g., /a/) and words to improve voice quality; subsequently, shift training to sentences and conversational speech
Topography.
Description of natural and physical properties of an object or event; topographic aspects of skills refer to their physical form or shape including how complex they are, and how they appear, sound, and feel.
Total Communication. The simultaneous use of multiple modes of expression to enhance communication; includes speech, gestures, informal and formal (e.g., American Sign Language and AMER-IND) signs, and facial expressions.
Tracheoesophageal Fistulization/Puncture (TEF/ TEP). A surgical procedure that helps laryngectomy pa-

Training Broad.
An approach to treating articulation disorders in which several sounds are treated simultaneously; practice, limited on any one sound, is given over a broad range of sounds; contrasted with Training Deep.
Training Criterion. A rule that specifies when an exemplar or a target skill has met a specified performance level; a 90% correct response rate is an often accepted training criterion. ● Specify a training criterion in measurable terms (e.g., 9 out of 10 correct responses) ● Continue training until that criterion is met ● Probe when the training criterion is met ● If the probe criterion (90% correct in untrained contexts) is not met, resume training
Training Deep. An approach to treating articulation disorders in which one or a few sounds are trained intensively; other sounds are selected for training only when the child has mastered the initial targets; contrasted with Training Broad.
Training Sessions in Natural Environments. Part of extraclinical training strategy used to promote maintenance.
● Initially, hold training in varied settings in and around the
clinic
● Next, hold informal training sessions in nonclinical settings ● Train parents to hold training sessions at home ● Take the client to such natural setting as shopping centers
and restaurants
● Let the training in natural settings be less conspicuous,
involving mostly conversational speech
● Prompt the target responses in a subtle manner ● Deliver reinforcers and corrective feedback in a subtle
manner 519

Transcortical Motor Aphasia Transcortical Motor Aphasia. A type of nonfluent aphasia characterized by agrammatic, paraphasic, and telegraphic speech; differential diagnosis is made on the basis of intact repetition skills; lesion or lesions, often sparing the Broca’s area, are found deep in the frontal lobe or above or below Broca’s area. See Aphasia; Treatment of Aphasia: Specific Types.
Transcortical Sensory Aphasia. A type of fluent aphasia that is similar to Wernicke’s aphasia; the lesion or lesions, often sparing Wernicke’s area, are found in the temporoparietal regions; characterized by fluent speech, poor auditory comprehension, impaired naming, paraphasic speech, and echolalia.
Traumatic Brain Injury (TBI) in Adults. An injury to the brain; may be Penetrating (Open-Head) Injury or Nonpenetrating (Closed-Head) Injury; major symptoms include restlessness, irritation, disorientation to time and place, disorganized and inconsistent responses; impaired memory, attention, reasoning, drawing, naming, and repetition; also known as craniocerebral trauma; immediate concern is medical; long-term concern is rehabilitation.
Treatment of Traumatic Brain Injury: General Principles ● Plan for long-term treatment and rehabilitation, especially
T
in the case of more severe injury
● Use direct behavioral treatment procedures, as they are
known to be effective; these include simplifying the tasks with shaping procedure, measurable, practical skill targeting instead of indirect underlying process training; and immediate positive reinforcement for skill management ● Schedule different kinds of therapeutic activities at different stages of recovery from TBI (acute, postacute, outpatient, and long-term) ● Work with the family and medical and rehabilitation staff from the beginning; make sure that the family members 520

(e.g., ‘‘Listen, carefully, now’’; ‘‘I want to say something to you.’’); educate the clinical staff to do the same ● Give introduction to new topic (e.g., ‘‘I am now going to tell you about . . .’’); do not introduce topics abruptly ● Assess comprehension of spoken speech frequently by asking the patient to restate what was just said or summarize the main points of discussion; prompt correct responses to minimize errors ● Reinforce nonverbal communication or signs of attention (e.g., eye contact, smiling, nodding); still, assess comprehension to make sure the patient understands ● Withhold attention from irrelevant, inappropriate, and tangential responses; without responding, ask a simple question that might evoke a more relevant response; reinforce it; use Time-Out to decrease more serious undesirable behaviors ● Reduce complexity and rate of speech if necessary ● Use statements instead of questions when initially communicating with the patient ● Prompt, gesture, and use verbal instructions to help the patient comprehend ● Allow the patient time to listen to instructions ● Use sentence completion tasks for patients with initiation or inhibition difficulties ● Place contingencies on appropriate behaviors Treatment During the Intermediate Stage ● Continue to place contingencies on target behaviors ● Establish more complex routines ● Teach the patient to request information (e.g., requesting information about time, space, or persons)
524
TBI: Treatment Procedures ● Continue to provide additional stimuli as needed (writ-
ten instructions, alarms, posters, verbal reminders of activities and appointments) ● Repeat treatment trials ● Improve selective attention and comprehension by asking the patient to: • match pictures to sentences • follow spoken instructions • retell a message to another person • answer simple questions ● Work closely with health care workers; teach them to • recognize the client’s problems • respond promptly to positive changes in communication skills • provide additional stimuli as needed ● Work with family members; teach them to • prompt the client when there is hesitation • model appropriate behaviors • reinforce the behaviors naturally and sustain those behaviors ● Increase awareness of deficits • use simple explanations to describe the problem to the patient • give contingent feedback on problem behaviors • use group therapy to allow the patient to see that others have similar problems ● Continue group treatment to have peer modeling, monitoring, and self-awareness of problems ● Begin to diminish special stimuli and reminders as performance improves toward the end of the intermediate stage ● Begin to teach Self-Control (Self-Monitoring) skills ● Begin to teach compensatory skills Treatment During the Late Stage ● Train more complex activities that enhance independence

a brief and simple story and ask the client to retell it; prompt correct responses; subsequently, tell progressively more complex stories the patient will retell; reduce the frequency of your prompts) Ask the patient to describe daily activities and complex skills (e.g., ask the patient to describe how he or she would fix a sandwich, make a grocery list, pay utility bills; prompt correct responses in correct sequence of steps; reinforce) Integrate such pragmatic skills as topic maintenance and topic initiation into narrative skill teaching (e.g., promote topic maintenance; prompt the patient to ‘‘Say more,’’ ‘‘Give details,’’ ‘‘What happened next?’’ ‘‘What about this?’’ or ‘‘What about that?’’; prompt the client to initiate conversation on new topics; fade the prompts) Integrate work-related words, phrases, and sentences if the patient is expected to return to work; make this activity client-specific Further diminish special stimuli (posters, verbal reminders, written instructions) that control behaviors Continue to use shaping, modeling, prompting, and manual guidance to enhance correct responses and to reduce the probability of errors Treat Motor Speech Disorders Teach Self-Control (Self-Monitoring) skills; teach the client to • keep possessions in specific places • count his or her own errors in treatment • self-correct errors • use self-cueing strategies (pausing after an error) Teach compensatory strategies if necessary, by teaching patients to: • break down tasks into smaller, more manageable components; teach the patients to write down steps 526
TBI: Treatment Procedures involved in performing an action (e.g., steps in preparing a breakfast) • request information relative to time, date, and so forth • request others to modify their speech (e.g., teach the client to request others to speak slowly or to repeat) • rehearse important information (e.g., teach the client to self-talk about how to perform such activities as fixing lunch or changing light bulbs) • write down instructions, appointments, important information, and so forth • ask for written instructions from people • use active instead of passive cues (an alarm instead of a reminder in a diary that may not be consulted) • use electronic devices (digital watches that display time, day, and date; auditorily signal appointments); use data bank watches that store messages and appointments; use electronic pill boxes that remind the patient to take medications; use microcassette recorders to record lectures, instructions, and discourse they can listen to later; use hand-held electronic spell checkers; use notebook computers for more complex information management • limit distractions or modify environment by finding quiet places to study or rearrange work environments • keep possessions at specific and constant places to improve access • cue himself or herself to activities, names, paces, and appointments ● Teach organizational strategies by teaching the patient to: • separate relevant from irrelevant material • summarize, highlight, and take notes • self-monitor ● Ask patients to copy symbols, letters, and words that commonly occur in their surroundings (e.g., signs that read, ‘‘No drinking, smoking, and eating’’) 527
T
TBI: Treatment Procedures ● Develop a core vocabulary that the patient is likely to
use every day
● Teach the patient to recognize letters, syllables, words,
phrases, and sentences
● Hold group treatment sessions; note, however, there is
T
no strong empirical evidence to support this, although it is a common practice; structure these group interactions to: • promote pragmatic communication skills (discourse, topic maintenance, and topic initiation) • increase general socialization • increase socially appropriate verbalization • self-evaluation of strengths and limitations ● Promote community reentry; note that rehabilitation should end with successful community reentry in which steps are taken to ensure a smooth transition from the rehabilitation setting to home, school, work, and the larger social situations • prepare the patient for reentry; in the final stages of treatment, emphasize self-help skills and independent living skills; stimulate the patient’s interest in academic, social, occupational, and household activities • educate family members, teachers, and supervisors about the current status of the patient; let them appreciate the patient’s strengths and limitations; let them understand the patient’s compensatory strategies and the continued support needed • modify the communication styles of family members and significant others to suit the remaining and perhaps permanent deficits (e.g., teach them to speak slowly, repeat often, and speak in simpler sentences) • modify the number and nature of demands people make (e.g., the teacher may give reduced amount of work or simplified work; work supervisor may have to give extra time to complete a task)

Treatment. Application of a variable that can induce changes; use of any effective procedure in teaching new communicative skills; behaviorally, management of contingent relations between antecedents, responses, and consequences; conceptually, a rearrangement of communicative relationships between a speaker and his or her listener.
Treatment of Communicative Disorders: General Procedures That Apply Across Disorders. Common procedures used in treating most if not all disorders of communication; modified to suit the individual client, his or her specific problems, the specific target behaviors, and in light of the performance data. ● Assess the client • determine the diagnosis • describe the strengths and limitations of the client • describe the client’s current level of communicative performance ● Evaluate the client’s family constellation • describe the family support and resources • describe the social, educational, or occupational demands made on the client ● Select functional, client-specific target behaviors • select behaviors that, when treated, will have the greatest effects on the client’s communication in social situations • select both short- and long-term targets • define the dismissal criterion ● Establish the pretreatment measures or baselines of target behaviors • select stimuli for evoking the target behaviors • repeat the measures to establish reliability • use the Baseline Evoked Trials and Baseline Modeled Trials 531
T
Treatment: General Procedures
T
• take an extended conversational speech sample • obtain home sample if possible ● Design a flexible therapeutic environment • use the degree of control and structure that is necessary • gradually, loosen the structure to make the treatment environment more like the client’s everyday environment ● Write a treatment program; specify • the target behaviors • treatment procedures • reinforcing or feedback procedures • Criteria for Making Clinical Decisions (moving from one level of treatment to another) • Probe procedure • maintenance procedure • follow-up • booster treatment ● Implement the treatment program • use objects, pictures, demonstrated actions, and so forth to evoke the target behaviors • give instructions, demonstrations, explanations • model the target responses • prompt the target responses • use manual guidance to assist the client in producing the target responses • shape the responses • fade the special stimuli including pictures, objects, modeling, prompts, and manual guidance • give prompt, positive feedback to the client; use natural reinforcers; if you used tangible reinforcers, fade them; decrease the amount of feedback given • give prompt, corrective feedback to the client; say ‘‘No’’ or ‘‘Wrong’’; use other procedures as found appropriate (time-out, response cost) • start treatment at a simpler level; however, if the client can perform at a higher level, do not use the lower level • probe for generalized production as often as necessary 532
Treatment: General Procedures • shift treatment, in progressive steps, to more complex levels as the client meets the probe criterion • always train the target behaviors in conversational speech with natural consequences ● Implement the maintenance program • train family members, teachers, friends, and professional caregivers in supporting the client’s communicative behaviors • teach them to evoke the target behaviors and reinforce the client naturally • shift training to nonclinical settings • invite other persons to treatment sessions • have family members conduct informal treatment sessions at home • have teachers focus on the target skills you teach and integrate those skills in the classroom work • teach the client to self-monitor his or her errors and target behaviors • teach the client to count his or her relevant behaviors • teach the client to self-correct mistakes • teach the client to cue himself or herself • teach the client to pause soon after an error response is produced • dismiss the client when responses are reliably produced in natural settings ● Follow up the client • set up a schedule for follow-up • follow up a client for a duration necessary to show maintenance • take a conversational speech sample during follow-up sessions • measure the production of relevant communicative skills • recommend booster treatment if the skills have deteriorated ● Arrange for booster treatment • give the same or better treatment 533
T
Treatment: General Sequence • probe the response rates • schedule the next follow-up if necessary Hegde, M. N. (1998). Treatment procedures in communicative disorders (3rd ed.). Austin, TX: Pro-Ed.
Treatment of Communicative Disorders: A General Sequence that Applies Across Disorders. Step-
T
wise progression of treatment used in treating disorders of communication; the sequence may be based on response topography, response modes, multiple targets, training and maintenance, and response consequences. ● Sequence and simplify the target behaviors topographically • syllables or words • phrases • sentences that are imitated or otherwise controlled • sentences that are more spontaneously produced • sentences that are fully spontaneously produced • conversational speech • begin treatment at the simplest level that is necessary for the client; do not routinely start training at the syllable or word level; experiment to see if the client can manage at a higher level ● Sequence the response modes • begin treatment with imitation as the initial response mode if necessary • move to evoked responses ● Sequence the multiple targets • teach the most useful behaviors earlier than the less useful ones • teach the simpler behaviors earlier than the more complex behaviors • teach first behaviors that are building blocks for other behaviors • when one target behavior reaches the probe criterion, select another behavior or shift training to more complex level on the behavior under training ● Sequence training and maintenance strategies 534
Treatment of Procedural Modifications • initially establish the behavior under structured clinical situations • loosen the structure gradually and make treatment conditions more similar to natural conditions • shift treatment to more natural conditions in and around the clinic • shift training to natural conditions away from the clinic • shift training to home situations, but do this as soon as possible (do not wait until the last stage of training) ● Sequence response consequences or feedback variations • give more frequent and consistent feedback in the beginning • reduce the amount of feedback as the learning stabilizes • give tangible reinforcers if necessary and only in the beginning • shift to social and more natural reinforcers • train others to give natural feedback in naturalistic settings Hegde, M. N. (1998). Treatment procedures in communicative disorders (3rd ed.). Austin, TX: Pro-Ed.
Treatment of Communicative Disorders: Procedural Modifications. Changes made in treatment procedures because of their ineffectiveness or less than optimum effectiveness; modifications may be made in antecedents, responses, and consequences; treatment procedures, not principles, are modified; based on performance data. ● Modification of antecedents • change stimuli that are ineffective in evoking the target responses • shift from pictures to objects • shift from line drawings to photographs • shift from abstract to concrete stimuli • shift from pictorial representation to enacted stimuli • discard clinical stimuli in favor of stimuli from the client’s home • model if evoking is not effective 535
T
Treatment Evaluation
T
• prompt if evoking is not effective • provide manual guidance (physical assistance to execute a response) if the evoking techniques are not effective • give instructions and repeat them • ask effective, common questions to evoke the responses • rephrase ineffective questions ● Modification of responses • simplify the response if a more complex topographic feature is ineffective (too difficult) • if the target is not produced in sentences, shift downward in progressive steps • abandon training on a behavior that is too difficult for the client in favor of one that is easier; use the baseline data for guidance • abandon training on a behavior that is not imitated in favor of the one that is • return to abandoned behaviors at later date; shape them in small steps ● Modification of consequences • use the operational definition of consequences; events should increase behaviors to be called reinforcers; decrease to be called punishers or corrective • change consequating events that do not increase behaviors • change consequating events that do not decrease behaviors • use primary reinforcers if social consequences do not reinforce • shift back to social reinforcers after the behaviors are established • use tokens backed up by a variety of reinforcers if other forms fail • use biofeedback if other forms fail Hegde, M. N. (1998). Treatment procedures in communicative disorders (3rd ed.). Austin, TX: Pro-Ed.
Treatment Evaluation. Testing the immediate effects and long-term efficacy of treatment procedures by controlled experimental analysis; an important criterion in treatment 536
Treatment Evoked Trials selection; see Treatment Selection Criteria; treatment evaluation involves: ● Group or single-subject experimental designs ● Comparison of treatment versus no treatment to show that treatment is better than no treatment ● Ruling-out of extraneous variables to show that it was the treatment, and not some other factor (e.g., maturation, teacher’s work, parents’ actions), responsible for the documented effects ● Replication by the experimenter and others to show that the technique is effective (or not effective) when applied in different settings, by different clinicians, and in treating different clients Hegde, M. N. (1994). Clinical research in communicative disorders: Principles and strategies (2nd ed.). Austin, TX: Pro-Ed.
Treatment Evoked Trials.
Structured and temporally separated opportunities for the client to produce a target response in the absence of clinician’s modeling; useful in establishing target behaviors, especially with clients who perform better under a highly structured treatment session. ● Place stimulus item in front of client or demonstrate an action ● Ask the relevant predetermined question ● Wait a few seconds for client to respond ● If the response is correct, reinforce the client ● If the response is incorrect, give corrective feedback ● Record the response on the recording sheet ● Remove stimulus item ● Wait 2–3 seconds to signify the end of the trial ● Begin the next trial ● Calculate the percent correct response rate
Treatment Modeled Trials. Structured and temporally separated opportunities for the client to produce a target response when the clinician models the response for the client to imitate. 537
T

General Comments About Treatment Selection.
T
Note that: ● Many treatment procedures in communicative disorders have not been experimentally tested to show that treatment is better than no treatment ● It is the ethical responsibility of clinicians to use techniques that have been shown to be effective in controlled experimental research ● It is necessary for clinicians to have a general knowledge of treatment research designs without which they cannot evaluate treatment procedures offered to them ● Many specialists vigorously advocate and offer ‘‘new and revolutionary’’ treatments in the absence of controlled experimental data ● Rejection of treatment procedures based solely on opinions, speculation, questionable theories, bandwagon, popularity, also is a clinician’s ethical responsibility ● Technique that appears logical, appealing, likeable, and so forth may not necessarily be effective ● Widespread use of a technique is not an assurance of its effectiveness
538
Treatment Selection Criteria ● Certain unpopular techniques (e.g., time-out and re-
sponse cost in the treatment of stuttering) are known to be effective, as shown by controlled research ● Speech-language pathology is not immune to faddish trends in treatment ● Getting on a bandwagon quickly is not the best sign of staying current in the discipline ● Some of the techniques you have been using with enthusiasm for years may never have been tested and may in fact be useless
Evaluating the Levels of Evidence to Select or Reject Treatment Procedures. Note that the criteria are hierarchically arranged based on the levels of evidence; a higher criterion is more stringent, more difficult to meet, although more preferable than a lower criterion; a treatment technique is accepted or rejected based on the level of evidence on which it is advocated: ● Level 1. Expert Advocacy. Some techniques are simply advocated by experts; no evidence of any kind is offered; may sound logical, appealing, and the advocate may be influential or well-known; reject all such procedures ● Level 2. Unreplicated, uncontrolled case studies. Some techniques may have been clinically tried with a few clients and a case study published; the study has not been repeated (replicated); no control groups or controlled conditions were used; clients have improved under treatment; no assurance that treatment was effective because extraneous variables have not been ruled out; because at least improvement with the technique was documented, you may select this type of treatment and use it with caution ● Level 3. Replicated, uncontrolled case studies. A technique has been applied more than once and multiple case studies have been published; no control groups
539
T
Treatment Targets or controlled conditions yet; clients have improved under treatment; such a technique may be used, although no one can claim that the treatment is effective ● Level 4. Unreplicated, controlled experimental studies. The technique has been experimentally evaluated with a control group or a single-subject experimental design with control conditions; treatment was shown to be effective by ruling out extraneous variables; but the generality and applicability of the technique is unknown because it has not been applied in different settings by different clinicians (replication); clinician can use a technique that has been experimentally verified; not just improvement, but effectiveness is claimed for the technique ● Level 5. Replicated, controlled experimental studies. A technique has been shown to be effective in experimental research and then shown to have generality by repeating its application in different settings, by different clinicians, in treating a variety of clients; therefore, this technique is the most desirable; this is the kind of technique the clinician would want to select Hegde, M. N. (1994). Clinical research in communicative disorders: Principles and strategies (2nd ed.). Austin, TX: Pro-Ed.
Treatment Targets. Skills or behaviors that are taught to
T
clients during treatment. ● Select treatment targets after a thorough assessment ● Select functional targets that are useful to the client ● Select targets that are linguistically and culturally appropriate to the client ● Select skills that can make an immediate and socially significant difference in the communicative skills of the client ● Select behaviors that serve as building blocks for more complex functional skills
Treatment or Teaching Versus Stimulation. See Stimulation Versus Treatment or Teaching. 540
Treatment Variables Treatment Variables. Technical operations performed by the clinician to create, increase, or decrease behaviors; these include: ● Antecedents or stimuli used in treatment, including modeling, instructions, demonstrations, manual guidance, pictures, objects, recreated events, storytelling (by the clinician), topics of conversation, and so forth ● Consequences or feedback the clinician gives, including verbal praise, tokens, tangible reinforcers, opportunities to indulge in various activities, privileges offered by parents, and so forth
Tremor. A pattern of shaking, defined as an involuntary rhythmical movement of small amplitude.
Trials. Measurable sequentially repeatable opportunities to produce a response; may be more or less structured; include Baseline Evoked Trials, Baseline Modeled Trials, Treatment Evoked Trials, and Treatment Modeled Trials.

Unconditioned Reinforcers Unconditioned Reinforcers. Reinforcers whose effects do not depend on past learning or conditioning (e.g., food items); the same as Primary Reinforcers; see Conditioned Reinforcers.
Unconditioned Response. A response given to unconditioned stimulus; typically a response without a conditioning or learning history (e.g., salivary response to food in the mouth); see Conditioned Response.
Unconditioned Stimulus. A stimulus that elicits a response without the benefit of conditioning or learning (e.g., food in the mouth that automatically elicits a salivary response); see Conditioned Stimulus.
Unilateral Upper Motor Neuron Dysarthria. A type of motor speech disorder; its neuropathology is damage to the upper motor neurons that supply cranial and spinal nerves involved in speech production; the dominant speech problem is imprecise production of consonants; select appropriate treatment targets and procedures described under Treatment of Dysarthria; Dysarthria: Specific Types.
Unilateral Vocal Fold Paralysis. Paralysis of one of the two vocal folds; leads to breathy voice and reduced intensity.

Validity Validity. The degree to which a measuring instrument measures what it purports to measure; treatment procedures may have Logical Validity, Empirical Validity, or both; procedures that have empirical validity are preferable to those with only logical validity.
Variable Interval Schedule (VI). An intermittent reinforcement schedule in which the time duration between reinforcers is varied around an average; not as applicable as the Fixed Interval or Variable Ratio Schedules in the treatment of communicative disorders; difficult to use in routine clinical work; efficient with electronic programming equipment.
Variable Ratio Schedule (VR). An intermittent reinforcement schedule in which the number of responses needed to earn a reinforcer is varied around an average; more effective in generating response rates that last; useful in a maintenance strategy. ● Vary the number of responses required for reinforcement from one occasion to the other ● Initially, reinforce on a smaller ratio schedule (e.g., a VR 4) and increase the ratio gradually (e.g., VR 6, VR8, VR12, etc.)
Velar Assimilation. A phonological process in which a velar sound is used in place of a nonvelar sound (e.g., /g/ for /d/); see Articulation and Phonological Disorders.
Velar Fronting.
A phonological process in which velar sounds are replaced by nonvelar sounds (e.g., /t/ for /k/); see Articulation and Phonological Disorders.
V
Velopharyngeal Insufficiency. Also known as velopharyngeal incompetence, a clinical condition in which the velopharyngeal mechanism cannot adequately close the velopharyngeal port, resulting in hypernasal speech; see Cleft Palate.
Ventricular Dysphonia.
A voice disorder resulting from the use of the ventricular (false) vocal folds for phonation; 546
Verbal Apraxia possibly because the true folds have some pathology; characterized by low pitch, monotone, decreased loudness, Harshness, and arrhythmic voicing. ● Teach the client to take a prolonged inhalation through the open mouth and sustained exhalation without phonation ● Teach the client Inhalation Phonation (this is usually true fold phonation) ● Ask the client to produce inhalation phonation–exhalation phonation on the same breath ● Ask the client to produce a matching exhalation phonation ● Have the client practice exhalation phonation ● Teach the client to vary the pitch ● Fade inhalation–exhalation; stabilize normal phonation in conversational speech
Verbal Apraxia. A motor speech disorder also known as apraxia of speech; characterized by difficulty in initiating and executing the movement patterns necessary to produce speech; not due to paralysis or weakness of the speech muscles; thought to be a motor planning disorder; see Apraxia of Speech.
Verbal Corrective Feedback. A method to reduce incorrect responses in treatment; feedback is presented soon after an incorrect response is made; includes such verbal feedback as ‘‘No,’’ ‘‘Wrong,’’ or ‘‘Not correct’’; often combined with Nonverbal Corrective Feedback.
Verbal Praise. A type of positive reinforcement in which the client is praised for giving correct responses or for imitating modeled responses; a response consequence known to increase the frequency of target behaviors. ● Praise the client promptly for producing or imitating a correct response ● Use such phrases as ‘‘Good Job!’’ ‘‘I like that!’’ ‘‘That was correct!’’ ‘‘Excellent!’’ and so forth; select the phrases and words that are appropriate for the client’s age, education, and cultural background 547
V
Verbal Prompt ● Deliver verbal praise in a natural manner, with appropriate
emotion and facial expression
● Keep an accurate record of response frequency to make
sure that the verbal consequences are indeed functioning as reinforcers (i.e., the response rate is increasing) ● Use other forms of reinforcers if verbal praise does not work (e.g., tokens or primary reinforcement)
Verbal Prompt. A verbal stimulus that helps evoke an unsure response; hints of everyday life; see Prompts.
Verbal Stimulus Generalization.
Production of unreinforced responses when untrained verbal stimuli are presented; measured on a Probe. ● Present the same physical stimulus as used in training (e.g., the picture of two books used in teaching an exemplar of the plural morpheme) ● Ask a question other than the one used in training to evoke the response (e.g., if you asked ‘‘What do you see?’’ on training trials, ask ‘‘What are these?’’ on these probe trials) ● Do not model and do not provide any response consequences ● Record the response ● Present at least 10 trials, each involving a different picture and probe question (different from the training question)
Vibrotactile Hearing Aid. A type of hearing aid that delivers sound by patterns of vibrations felt on the skin; a good supplement to speech reading
Visual Alerting Systems. A variety of Assistive Listening
V
Devices for the deaf; generate visual signals (light) that alert the person to incoming phone calls, door bells, and smoke alarms; see Aural Rehabilitation.
Vocal Emphasis. A treatment technique in which the target feature within a word, phrase or sentence is highlighted in some manner while modeling it
548
Vocal Fold Paralysis ● In articulation treatment, emphasize the target phoneme
with extra stress, increased loudness, or a slight prolongation
● In language treatment, emphasize the grammatic mor-
pheme or other featured modeled in phrases and sentences with similar devices
Vocal Fold Paralysis.
Unilateral or bilateral paralysis of the folds that results in fixated fold or folds; unilateral more common; often due to trauma or accidental cutting of the recurrent laryngeal nerve; results in aphonia or dysphonia; Teflon or collagen may be injected into the paralyzed fold to make it bulge and help approximate; collagen is currently preferred over Teflon; concern is more medical in the case of bilateral vocal fold paralysis because of such associated problems as weakness or paralysis of the tongue, pharynx, or velum; respiratory survival and feeding are the main concerns; in the case of unilateral vocal fold paralysis, voice therapy may be appropriate, although the effects may be temporary and the goals may be limited to having the client produce functional voice: ● Model and reinforce a higher-pitched voice that might improve the voice ● Use the Half-Swallow Boom ● Use Digital Manipulation of the Larynx ● Try different Head Positioning maneuvers
Vocal Fry.
Popcorn popping or bubbling type of voice occurring toward the lower end of the pitch range; may be slightly hoarse; a normal characteristic that may be abnormal if exhibited too frequently.
Vocal Hyperfunction. Vocally abusive behaviors that cause nodules, polyps, and associated voice disorders; specifically, speaking with excessive muscular effort and force. ● Assess the disorder to find out the specific kinds of vocally abusive behaviors the client exhibits
549
V
Vocal Jitter ● Reduce the vocally abusive behaviors ● Experiment with different Specific Normal Voice Facilitat-
ing Techniques (described under Voice Disorders) to promote normal or vastly improved voice ● Use those techniques to teach the client the more relaxed and normal voice production
Vocal Jitter. Pitch perturbations; a cycle-to-cycle variation in frequency that exceeds 1%.
Vocally Abusive Behaviors. A variety of behaviors that
V
negatively affect the laryngeal mechanism and result in voice disorders; intervention described under Voice Disorders; Treatment of Vocally Abusive Behaviors; include the following: ● Excessive talking, singing, or humming ● Abusive singing habits (e.g., singing at inappropriate pitch levels, with poor laryngeal positions, with poor general posture, trying to maintain singing levels that exceed the singer’s capabilities) ● Constant and excessive religious chanting ● Excessively loud talking or singing ● Whispering ● Yelling, cheering, and screaming ● Excessive and chronic coughing and throat clearing ● Constant or excessive talking or singing during episodes of allergy, upper respiratory infection, and during menstruation ● Hazardous occupational use of voice (teaching, preaching, sports coaching, aerobic instruction, cheering, pep club activities, and political campaigning) ● Smoking and constant exposure to smoke (secondhand smoke) ● Excessive alcohol intake ● Constant and excessive grunting during exercises ● Habitual name shouting (calling) from a distance ● Constant talking in noisy environments (e.g., bars, sports arenas, construction sites)
550
Vocal Nodules ● Speaking with hard glottal attack ● Singing or talking at the upper or lower end of the pitch
range
● Excessive crying or laughing ● Inadequate fluid intake ● Playing with excessive vocal activity (making loud me-
chanical and animal noises during pretend play)
● Frequent pushing or lifting heavy objects ● Forceful effort during bowel movements
Vocal Nodules. Benign lesions of the vocal folds; generally bilateral; found in the anterior one-third and posterior twothirds of the true vocal folds; symptoms may include Hoarseness, Harshness, periodic Aphonia, frequent throat clearing, Hard Glottal Attacks, tension, and a dry vocal tract; result of vocal abuse; voice therapy designed to reduce vocally abusive behaviors is preferred over surgical intervention; see Treatment of Vocally Abusive Behaviors under Voice Disorders; essentially: ● Prescribe mandatory vocal rest if surgery has been performed to remove the nodules ● Reduce Vocally Abusive Behaviors ● Increase the breath support for speech ● Reduce vocal intensity ● Use Specific Normal Voice Facilitation Techniques (described under Voice Disorders) to teach the client to produce healthy voice
Voice Disorders. Various disorders of communication related to faulty, abnormal, or inappropriate phonation, loudness, pitch, and resonance; causes include vocally abusive behaviors, trauma to the laryngeal mechanism, and physical diseases; many treated both medically and behaviorally; some only medically; others only behaviorally. ● Voice Disorders of Loudness. Socially inappropriate voice that is too loud or soft.
551
V
Voice Treatment: General Principles ● Voice Disorders of Pitch. Voice characterized by inappro-
priate pitch; speech at the low end of one’s pitch range, which requires too much effort and force; or speech at the high end of the range, which causes fatigue. ● Voice Disorders of Phonation. Voice problems that result from vocal folds that are altered by vocally abusive behaviors, trauma, or diseases; voice that is characterized by varying degrees of breathiness, hoarseness, harshness, and pitch and loudness deviations. • Voice Disorders of Phonation: Abuse-Based. Such voice problems as hoarseness, breathiness, and harshness that result from vocal abuse, which often causes physical changes in the vocal folds • Voice Disorders of Phonation: Physically Based. Such voice problems as hoarseness, breathiness, and harshness that result from physical diseases; varied voice problems associated with laryngeal trauma. ● Voice Disorders of Resonance. Voice characterized by inappropriate resonance including Hypernasality and Hyponasality.
Treatment of Voice Disorders: General Principles
● Make a thorough assessment of voice disorders; consider
the cited sources and PGASLP
● Consider the goal of voice therapy as normal sounding
voice with little or no effort and tension
● Make a thorough evaluation of the voice disorder ● Make an assessment of the client’s vocally abusive behav-
iors at home and in other natural settings

vocally abusive behaviors with those that facilitate efficient and normal voice production Individualize the facilitating techniques, because what works with one client may not work with another The first priority in treating voice disorders in most children is to reduce vocally abusive behaviors, and the second priority is to teach optimal vocal behaviors Generally, the first priority in treating voice disorders in adults is to teach optimal vocal behaviors, and the second priority is to reduce vocally abusive behaviors Work closely with parents and others to help reduce vocally abusive behaviors and to reinforce healthy vocal behaviors Establish baselines of vocally abusive behaviors and the frequency of abnormal voice productions in and outside the clinic
Treatment of Disorders of Loudness and Pitch General Procedures ● Rule out hearing loss before you attempt modification of loudness ● Establish the baseline loudness or pitch of the client ● Discuss the problem with older children and adults ● Give feedback on the client’s problematic loudness or pitch by tape-recorded samples of the client’s speech and your speech for comparison ● Reinforce a range of acceptable loudness and pitch variations, because vocal intensity and pitch vary across speaking situations ● Role play different speaking situations and reinforce appropriate loudness and pitch levels ● Use such biofeedback instruments as the Vocal Loudness Indicator, Visi-Pitch, and any available computer programs for voice therapy to increase shape the desired loudness and vocal pitch ● Promote maintenance of the new vocal loudness and pitch in natural settings by shifting treatment to such 553

settings and by teaching Self-Control (Self-Monitoring) skills Treatment of Excessively Loud Voice. Shape progressively softer voice in a client with too loud voice: ● Educate the client about his or her excessively loud voice; tape-record a sample of loud voice and let the client hear it; contrast it with soft voice recorded alternatively ● Instruct, demonstrate, and model voice at different loudness (e.g., whispered voice, a quiet voice that would not wake up a sleeping person, normal conversational voice, loud and louder voice) ● Model a quiet voice for the client and ask him or her to imitate it; use computerized program such as the VisiPitch to give visual feedback on intensity changes ● Start with words and phrases and move on to conversational speech; reinforce speech produced at desired intensity ● If it is necessary to start with a louder voice, reinforce progressively softer voice until the level is acceptable Treatment of Excessively Soft Voice. Shape progressively louder voice in a client with too soft voice: ● Make sure that the excessively soft voice is not due to such physical problems as hearing loss and vocal fold pathology ● Tape-record a speech sample to give feedback to the client about the excessively soft nature of his or her voice ● Experiment with pitch changes to see if a slight increase in the pitch level might produce a slightly louder voice; if so, teach the client to speak at that level ● Experiment with increased subglottic air pressure to see if loudness would improve; if so, ask the client to practice speaking with such increased air pressure ● Use the auditory masking on an audiometer to induce the Lombard effect (increased vocal intensity under au554

ditory masking); fade the noise gradually and let the client practice louder speech Use the Pushing Approach (described later in this section under Specific Normal Voice Facilitating Techniques) only if instruction, modeling, and biofeedback fail Model the desired loudness frequently Shape a progressively louder voice with procedures such as these Reinforce progressively louder voice until the level is acceptable
Treatment of Pitch Disorders Treatment to Raise the Baseline Pitch ● Instruct the client on pitch, its variations, and acceptable range ● Model different levels of pitch for the client ● Experiment with the client to see if he or she can produce a desirable pitch even if briefly ● Tape-record the client’s desirable pitch and use it as a model for self-imitation ● Provide also a live model or a mechanical model on such computerized instruments as Visi-Pitch, B & K Real-Time Frequency Analyzer ● Use such instruments to give immediate feedback during training trials or durations ● Begin treatment with single words, preferably those that begin with vowels; have the client produce them with the desirable pitch ● Increase the response complexity by moving to words, phrases, sentences, and conversational speech ● Use oral reading to stabilize the desired pitch ● Provide mechanical as well as live social reinforcers ● Implement a maintenance program by conducting informal treatment in nonclinical settings ● Encourage the client to use the new pitch in all speaking situations 555
V
Voice Treatment: Phonation Disorders ● Train family members, teachers , and others to prompt
the client to use the new pitch and reinforce when he or she does Treatment to Lower the Baseline Pitch ● Use the same procedures used for raising the pitch except for setting a lower pitch as the target ● Lower the pitch in carefully graded steps, if necessary
Treatment of Disorders of Phonation
V
Treatment of Abuse-Based Disorders of Phonation ● Make an assessment of vocally abusive behaviors ● Eliminate or reduce vocally abusive behaviors; use procedures described later in this section ● Refer the client for periodic medical examinations ● Make periodic assessment of voice if and when the medical or surgical treatment is repeated ● Follow up the client to ensure that vocally appropriate behaviors are maintained Treatment of Physically Based Disorders of Phonation ● Refer the client with voice problems to a medical specialist to have an assessment of the physical bases of the problems ● Work closely with the medical professionals who treat the physical diseases or laryngeal trauma ● Provide voice therapy following medical or surgical treatment if found necessary and useful ● Tailor treatment to the residual problem; consider teaching proper and optimal use of voice and appropriate loudness and pitch. ● Treat patients with Laryngectomy with appropriate communication rehabilitation techniques ● Make periodic assessments of voice if and when surgical treatments are repeated
Treatment of Disorders of Resonance: General Principles ● Make an assessment of the specific resonance problem:
Hypernasality or Hyponasality. 556
Voice Treatment: Vocal Abuse ● Rule out the presence of cleft palate or congenital pala-
topharyngeal incompetence as the source of resonance problems; do not offer behavioral voice therapy for such cases unless the organic problems are eliminated or significantly improved by surgical or prosthetic means, and clients are now good candidates for voice therapy • work with the prosthodontist in the client-specific fabrication of a prosthetic device • assess speech before and after surgical and prosthetic treatment ● Use biofeedback instruments to monitor and reinforce appropriate oral and nasal resonance Treatment of Hypernasality ● Assess Hypernasality and treat it only when there is adequate or at least marginal velopharyngeal adequacy and the disorder needs behavioral management ● Use treatment procedures described under Hypernasality Treatment of Hyponasality ● Assess Hyponasality and treat it only when it is clear that too broad a pharyngeal flap or too big an obturator bulb is not the source of reduced nasality ● Be aware that very few persons exhibit hyponasality with no physical basis ● Use treatment procedures described under Hyponasality
Treatment of Vocally Abusive Behaviors
● Make a thorough assessment of vocally abusive behaviors;
consult the cited sources and the PGASLP
● Educate the client and the family about the harmful results
of vocally abusive behaviors the client exhibits; use charts and diagrams to show vocal nodules and how they affect voice ● Impress on the client and the family members the relationship between abusive behaviors and the resulting vocal pathology and voice disorders ● Through case history and interview, identify all the vocally abusive behaviors of the client; identify the conditions 557

real-time feedback may be the most effective in modifying speech quality. ● Use an instrument such as the Kay Facilitator (Kay Elemetrics), which provides real-time amplified feedback of client’s voice through head phones; also provides delayed auditory feedback, loop feedback, metronomic pacing, and masking noise ● Ask the client to listen carefully to his or her voice as the feedback is provided; teach the client to use a different voice facilitation approach (e.g., chanting or glottal fry) ● Ask the client to pay attention to improvement in voice quality when a facilitating approach is used; contrast this with the typical deviant voice of the patient Chant-Talk Method. A voice therapy technique in which words are spoken in a connected manner, with even stress, prolongation of sounds, soft glottal attack, and continuously with the absence of stress for individual words; recommended for clients with hyperfunctional voice including Hard Glottal Attacks. ● Ask the patient to reduce the effort required to speak ● Play a recording of a chant and model the method ● Ask the patient to imitate the tape-recorded production by using a chant ● Ask the patient to read aloud by alternating the chant voice with the regular one ● Ask the patient to read for 20 seconds at a time ● Playback oral reading samples of the patient’s voice and ask him or her to differentiate the chanted voice from the normal one ● Fade the chant and maintain normal voice without the chant Chewing Technique. A voice therapy technique that requires patients to imagine that they are chewing food while voicing; recommended for reducing vocal hy560

Physical manipulation of the larynx to promote desirable voice quality; may be used to reduce vocal pitch and decrease laryngeal tension. ● Use digital pressure to lower the pitch • Ask the patient to prolong a vowel • Apply slight finger pressure to the thyroid cartilage as the vowel is prolonged (the pitch will drop) • Fade the digital pressure and let the client practice the lower pitch ● Lower the larynx to reduce tension • apply a slight downward pressure with the middle finger and the thumb just above the thyroid notch • ask the client to prolong vowels with the larynx in the lowered position • use other voice facilitating techniques • fade the downward pressure on the larynx Glottal Attack Changes. Modifying either hard glottal attacks in whom they are a problem (typically in persons who abuse their voice) or inducing slightly harder 561

glottal attacks, which may be beneficial to some (typically in persons with unilateral vocal fold paralysis); thus, the method includes two opposite manipulations applied to opposite problems. ● Reduce hard glottal attacks • educate the client about the harmful effects of hard glottal attacks • model and demonstrate hard and soft glottal attacks; tape-record the client’s hard glottal attacks and let the client listen to them to understand their characteristics • begin training on soft initiation of voice with monosyllabic words that contain the /h/ in the initial position; when the client learns to initiate the /h/ words softly, train with words containing initial unvoiced consonants and then with words containing vowels • shape gentle onset with whisper as the initial response; ask the client to whisper the initial vowel and increase the intensity gradually until a soft phonation is heard • use also the yawn-sigh method to reduce hard glottal attacks • use also the chant to reduce hard glottal attacks • use simultaneous chewing and chanting to reduce hard glottal attacks • increase the response complexity gradually until the client produces conversational speech with soft glottal contacts ● Teach harder glottal attacks • educate the client about hard and soft forms of voice initiation • demonstrate and model harder glottal attacks by producing such words as pop, peep, bob, and beet in a sudden plosive manner; ask the patient to imi-
562
Voice: Specific Facilitating Techniques tate them and reinforce imitated or approximated productions • prove visual feedback of soft and harder glottal attacks on an oscillograph or Visi-Pitch • use the pushing approach briefly to induce harder glottal attacks • increase the response complexity gradually to induce better approximation of vocal folds in conversational speech Glottal Fry. A normal voice characteristic useful in treating voice disorders associated with vocal nodules, polyps, fold thickening, functional dysphonia, ventricular phonation, and spasmodic dysphonia; produced with relaxed vocal folds, minimal vocal fold tension, and minimal airflow. ● Educate the client about relaxed vocal folds being better able to approximate in spite of the nodules and other masses on them ● Teach the client to say /i/ softly after a slight exhalation ● Ask the client to ‘‘Open the throat’’ and make the sound deep, with a slow series of pops ● Ask the client to produce the same tone on inhalation to see whether the fry is better produced on inhalation or exhalation because individuals differ; alternate between inhalated and exhalated phonations ● Ask the client to say words like on and off and in and out while producing the fry; tape-record the client’s productions that will serve as a model ● Teach phrase or short sentence productions in the fry mode; ask the client to say ‘‘Easy does it,’’ ‘‘Squeeze the peach,’’ or ‘‘See the eagle’’ and point out the improved voice quality to the client ● Ask the patient to practice speech in the fry mode at home

yngologist; as the voice improves, they are likely to improve as well Half-Swallow Boom. A method of treating low loudness and air wastage from the vocal folds; recommended for clients with Unilateral Vocal Fold Paralysis or Mutational Falsetto. ● Ask the client to swallow and, as this action is still in progress, say ‘‘boom’’ ● Let the client produce ‘‘boom’’ in a low-pitched voice ● Ask the client to say ‘‘boom’’ louder and with less breathiness ● Have the client discriminate the normal production from the ‘‘‘boom’’ production with the help of taperecorded samples ● Teach the client to turn the head first to one side and then to the other and say ‘‘boom’’ each time ● Lower the chin while saying ‘‘boom’’ ● Ask the client to add sounds and words to ‘‘boom’’ (e.g., ‘‘boom /i/’’; ‘‘boom one’’) ● Teach the client to add phrases and sentences ● Fade out the boom and swallow ● Ask the client to lift the chin up and bring the head back to the midline as he or she produces normal speech Head Positioning. Manipulation of head positions to promote better voice quality; recommended especially for clients with neurological disorders including dysarthria; may be used with clients who have hyperfunctional voice. ● Give instructions, model different head positions, demonstrate their effects on voice, and justify the procedure to the client ● Experiment with different head positions to find the one that promotes better voice (e.g., head rotated 564
Voice: Specific Facilitating Techniques toward left or right; neck flexed downward with the face looking down); ask the client to produce some prolonged vowels (e.g., /i/, /I/, /o/, or /u/) as different head positions are tried to identify the best position ● Ask the client to hold the head position that helps produce the best voice ● Ask the client to produce words, phrases, and sentences ● Gradually fade the unusual head position into a more normal position Inhalation Phonation. A technique of voice therapy designed to evoke true vocal fold vibrations in clients who are aphonic or those who exhibit ventricular phonation. ● Raise your shoulders, inhale, and phonate a highpitched hum ● Raise your shoulders, inhale, phonate the highpitched hum and lower the shoulders; exhale, and produce the same sound; repeat this ● Teach the patient to produce inhalation phonation ● Teach the client to produce inhalation and exhalation phonation with corresponding shoulder movements ● Demonstrate the movement from the high-pitched voice to the exhaled low-pitched voice ● Reinforce the client’s attempts to bring the pitch down ● Fade the shoulder movements ● Have the client practice single words until a normal sounding voice is stabilized ● Move on to more complex responses (phrases and sentences) Laryngeal Massage. A technique of voice therapy in which the laryngeal area is gently massaged and manipulated to improve vocal quality; recommended for clients with functional voice disorders with no organic 565

component characterized by a larynx that is positioned high during speech with some evidence of neck tension; some clinicians first try yawn-sigh with these clients and use laryngeal massage if the first attempt fails. ● Ask the client to prolong vowels as you massage the larynx through the steps specified ● Encircling the hyoid bone with the thumb and the middle finger, make a circular motion with your fingers while applying light pressure ● Repeat the procedure, this time with the fingers working posteriorly from the thyroid notch ● Repeat the procedure at the posterior borders of the thyroid cartilage ● Gently move the larynx in downward and lateral directions by placing the fingers over the superior borders of the thyroid cartilage ● Reinforce any improvement in the client’s voice Masking. A technique of voice therapy to treat clients with functional aphonia and those with poor voice quality because of inadequate auditory monitoring of one’s own voice; masking noise introduced through headphones. ● Use a standard audiometer to introduce masking noise; do so without any explanation ● Ask the client to read orally; turn the masking on and off for brief periods ● Tape-record the client’s reading to document possible changes in voice quality or the emergence of voice in the whispering aphonic patient ● Playback the tape-recorded sample to demonstrate improved voice quality or voiced productions by an aphonic client; contrast voice with and without masking ● Ask the client to match his or her improved voice or emergence of phonation without masking
566
Voice: Specific Facilitating Techniques ● Have the client read aloud under masking and, as
the voice improves or phonation emerges, abruptly end masking; repeat this process until the client can sustain the gains Nasal/Glide Stimulation. A voice treatment technique in which nasal glide consonants are used to promote better voice quality in patients with functional dysphonia, spasmodic dysphonia, and voice problems associated with vocal fold thickening, nodules, and polyps; words loaded with nasal glides seem to be produced with least effort. ● Prepare a list of words with nasal consonants in them (e.g., man, moon, many, morning, many men, moon man, morning singing) ● Prepare also a list of words that are repeated with /a/ inserted between repetitions (e.g., man a man a man or wing a wing a wing; use this list as an alternative) ● Prepare a list of words with glide consonants /r/ and /l/ combined with nasal sounds (e.g., marrow, married women, only lonely memory, Laura ran around) ● Prepare a list of words with /l/ and /r/ that are repeated with /a/ inserted between each repetition (lee a lee a lee or rah a rah a rah) ● Have the client practice the selected words; reinforce improved voice quality ● Gradually move on to words, phrases, and sentences containing other consonants to improve voice in meaningful, spontaneous speech Open-Mouth Approach. Oral openness during speech to increase oral resonance, reduce speaking effort, induce more relaxed speech, and to promote appropriate loudness, pitch, and quality of voice. ● Give feedback on lack of mouth opening during speech; use a mirror if necessary
567
V
Voice: Specific Facilitating Techniques ● Model greater and reduced oral openness; use a pup-

pet (greater mouth opening); contrast that with the speech of a ventriloquist (minimum mouth opening) ● Ask the client to imitate the two ways of speaking that you model ● Ask the patient to tilt the head down and speak ● Teach the client to self-monitor oral openness in natural settings ● Let the client practice speech with oral openness and reinforce for doing so Pushing Approach. A voice therapy technique to promote better approximation of vocal folds; appropriate for increasing vocal loudness. ● Instruct and demonstrate pushing ● Ask the client to push down on the arm of the chair or push up by trying to lift the chair by gripping the bottom of the seat while seated ● Ask the client to phonate and push simultaneously ● Reinforce the louder voice that typically results ● Increase the length of utterances with the louder voice ● Fade pushing Relaxation Training. A method to teach deep muscle relaxation with or without the help of biofeedback (e.g., electromyographic feedback); recommended for clients with excessive tension, anxiety, and stress; may be appropriate for some voice clients because of their excessive muscle tension. ● Use biofeedback instruments ● If no instruments are used, give instructions to contract and relax muscles ● Teach the client to discriminate between tensed and relaxed muscles by alternately asking him or her to tense and relax selected muscles (e.g., shoulder, neck, or jaw muscles)
568
Voice: Specific Facilitating Techniques ● Select facial, neck, and head muscles for relaxation
training; ask the client to relax one set of muscles and tense them to appreciate the difference ● Manipulate head positions to induce relaxation ● Ask the client to imagine speaking situations that induce greater tension and immediately let the client relax the speech muscles ● Use relaxing head movements (positions) if necessary ● Use other appropriate voice therapy techniques in combination with relaxation ● Stabilize a relaxed speaking posture and improved voice quality Respiration Training. Teaching clients to manage inhalation–exhalation cycles optimally for the purpose of phonation and sustained vocalization; recommended for clients with functional voice disorders who do not seem to use their breath stream properly in voice production. ● Explain the relation between breathing and speaking and between airflow and vocal fold vibrations ● Teach the client to inhale more quickly, more deeply than usual but exhale more slowly and in a controlled manner; to extend exhalation, ask the client to count to 5 slowly and then to 10 slowly ● Ask the client to prolong vowels to teach controlled and prolonged exhalation that would better support speech; in progressive steps, teach the client to prolong a vowel for about 20 seconds ● Teach the client to inhale quickly between utterances ● Teach good posture, which promotes normal airflow management Tongue Position Modification. Manipulating tongue position in the oral cavity to affect changes in voice quality and resonance; tongue typically positioned too far back results in cul-de-sac resonance; tongue typically

A voice therapy technique that requires little or no talking, typically for 4–7 days; vocal rest may be complete or partial. ● Recommend mandatory vocal rest for clients who have undergone any form of laryngeal surgery; this helps promote normal healing of the surgical wounds ● Recommend vocal rest as initial treatment for clients who have such types of laryngeal lesions as vocal fold hemorrhage and mucosal tear to let the healing process begin ● Recommend partial (modified) vocal rest for clients who have a severe cold (and resulting laryngeal inflammation), vocal nodules, and vocal fold edema; note that partial vocal rest means talking only when absolutely essential and with appropriate vocal habits ● Instruct the client either to totally avoid or markedly reduce • speaking • shouting or screaming • singing or humming • whispering • coughing or throat clearing • laughing or crying • lifting or pushing heavy objects ● Have a family member monitor these activities ● Teach the client to keep a record of such activities ● Teach the client to self-monitor
570
Voice: Specific Facilitating Techniques Warble Tone Approach. A voice treatment method in which the vocal pitch is constantly and continually shifted up and down to move the client out of the habitual monotonous pitch and thus to establish a pitch that is more appropriate to the client; recommended for clients with hoarse, strained, breathy, or rough voice regardless of its origin. ● Using a visual feedback device (such as the VisiPitch), model a tone that is varied up and down in pitch and ask the client to imitate what you model ● Ask the client to produce the vowel /i/, constantly varying the pitch (loudness should also vary with it); when the most desirable tone is heard, ask the client to extend it ● Begin fading the warble tone after a few successful trials; ask the client to reduce the warble portion of the tone and extend the steady, desirable portion of the tone; give several trials ● Withdraw the warble completely and have the client practice the desirable steady tone ● Introduce phrases with vowel-initial sounds in the first word of the phrase (e.g., even now, easy day), and ask the client to produce them with the new steady, desirable voice ● Use more complex utterances and sentences to stabilize the new voice Whisper-Phonation Method. A voice therapy technique that uses Prephonation Airflow to reduce Hard Glottal Attack; the client is required to whisper sustained vowel productions; gentle phonation is introduced as the vowel is being sustained. ● Ask the client to whisper monosyllabic words that have vowel initiates ● Teach the client to whisper the initial vowel very gently
571
V
Voice: Specific Facilitating Techniques ● Introduce gentle phonation as the end of the vowel
is prolonged
● Gradually increase the loudness of the whisper until
phonation is introduced
● Teach the client to blend the whisper into a soft
phonation
● Reinforce speaking in a relaxed, breathy voice
V
Yawn-Sigh Method. A voice therapy technique for clients with hypervocal function; uses the relaxing effects of the inspiratory yawn followed by an expiratory sigh and phonation. ● Instruct and demonstrate the relaxing effects of prolonged inspiration involved in a yawn and the relaxed phonation that results with a sigh ● Ask the client to yawn and then exhale slowly while phonating lightly ● Ask the client to say words that start with /h/ after each yawn ● Teach the client to produce a gentle, voiced sigh while exhaling ● Teach the client to produce an easy, prolonged, open-mouthed exhalation after each yawn ● Ask the client to skip the yawn and teach the client to inhale normally and exhale a prolonged sigh with the open mouth ● Ask the patient to say ‘‘hah’’ after beginning each sigh ● Ask the patient to say additional words all beginning with the glottal /h/ ● Ask the patient to blend in an easy, relaxed, phonation during the middle of a sigh ● Fade the sigh and move on to words, phrases, and sentences Andrews, M.
